Because you don’t know what the one item a customer HAS to have is. I told the GM of my grocery store that because he did not carry Apple Store gift cards on his rack he was losing at least 2 trips a month from me. I don’t let myself have more than I budget for my game, I don’t want to use a credit or debit card for it. So every time I wanted to buy that gift card he was losing the whole sale to a store that DID carry them.

They appeared on the rack a week later.

A lot of good answers, as there are a lot of reasons carry large inventory. I'll add.

Grocery stores carry a large range of items to draw customers in.

Think of that one product you love, that is hard to find but you know the one store in your area that carries it. They know you buy it every now and then, and they know it's not a common item.

Carrying that one item (and the other less common items people like) brings you into the store and you'll most likely buy more while you are there.

It can often function a bit like an AA vs a Bachelor's degree - where after so many credits you can 'apply' for the AA.

In a doctorate program you usually have 2-3 years of coursework followed by a dissertation, which can take one to forever years. At least in my program at the University of Florida you could apply for the masters if you've completed the coursework. Often times, graduate programs that end with a masters degree are geared towards a specific vocation or profession, such as a MBA for business. In political science, the masters/grad programs were geared toward students wanting to enter something like public policy instead of academia/research.

In terms of waste, some of these stores also have partnerships with food banks and other local nonprofits to donate nearly expired goods. They will also have buy one get one sales around a week before expiry and other promotions to get rid of things that are just sitting on shelves. Yes there’s a lot of waste but there’s also good ways to manage it accordingly.

Yes. If you want a credit card, you must have an indefinite contract at work so that they can be sure that you have enough funds to pay it off. The amount of the allowed minus is usually 2-3 monthly salaries. As for the loan: also an indefinite contract. The amount depends on the salary, the monthly installment cannot exceed, I think, more than 1/3 of the salary. For some loans, you need a deposit or proof that you have the ability to repay such a large loan (usually proof of ownership of real estate or perhaps shares). And housing loans are most often taken out with a mortgage. You "give" the apartment you buy on credit as a cover for the loan you use to buy that apartment. When you pay off the loan, the apartment is 1/1 yours. That's how we bought an apartment... that is, we are in the process of buying it. We haven't paid all of it yet. People who are employed in government companies are the best candidates since it is very difficult to get fired there. So bank is sure you are going to be able to pay. Credit cards and shopping cards follow the principle of a permanent order (lietral translation). The bank collects its installment automatically every month until it's all paid out. You don't have an option where you don't pay, unless you don't have funds in the account, but usually payments are made from the current account - the one on which your salary is deposited.

First, I'll try to give you the intuition of why it doesn't work like that:

Imagine you have one regular die 1-2-3-4-5-6, and another die with colours instead Blue-Red-Yellow-Green-Orange-Pink.

You roll the first die and obtain 6, that was a 16%.

You then roll the second die. What would that mean to "have a smaller chance to roll a 6 again"? Which colour is "6"? Is that Pink because it was the last of my list? That's completely arbitrary. It doesn't make sense that my first roll with change the probability of obtaining a colour or another, so there is also a 16% chance of obtaining each colour.

Now, if I write some numbers on top of the colours, does that magically change the probability of obtaining the "Pink 6" just because I obtained a 6 before? Surely not.

And if instead I rolled the first die a second time, why would that be any different? It's not like objects have some "magical memory" that remember how often it rolled 6.

Now, here is why you did think it worked like that in the first place:

If you roll the first die, don't look at its result, then roll the second die, then yes, the probability of getting two 6s is quite low: 1/36 = 3%

Similarly, if you roll the first die, don't look at its result, then roll the second die, and then I look at both and say 'I promise you that there is at least one 6', then the probability of a double 6 remains quite low: 1/11 = 9%. What's the difference? Well, I didn't tell you whether the first or the second was a 6, so you have less information than in your example (where you knew that it was the first who was a 6). Just a slight change in information and the probability is different.

And lastly, in nature, there is a lot of things that look random but aren't. For example, there is a 50/50 chance of being night or day, but after enough night the day eventually come, because that's not actually random in the same way a die works.

But in the situation you described:

  • You have total knowledge about the first roll. It's a 100% chance of obtaining a 6 because you know the 6 happened. That's a fact that cannot be changed.
  • You have zero knowledge about the second roll. It's a 16% chance of obtaining a 6 because the roll is fair and nothing is influencing it.

Yes, thank you for telling me you can’t research or read. Here, I’ll help you.

Research on how limited options reduce consumer spending; https://journals.sagepub.com/doi/abs/10.1509/jm.11.0495?journalCode=jmxa Page 10; https://www.ccrrc.org/wp-content/uploads/sites/24/2014/03/wasted-food-IP.pdf

Research on the amount of food wasted by grocery stores per year; https://www.usda.gov/foodwaste/faqs

Next time before you gloat over an “I gotchya moment”, you might want to step back and ask yourself if you really know what you’re talking about.ask yourself, “have I actually read anything on this subject or am I just a lame keyboard warrior who’s angry at the world”.

Have a nice day.

I am not sure that applies generally. I would say it is more that undergrad is generalized, while grad school is usually more focused.

As a chemical engineer, undergraduate was pretty much all general stuff that could be used in real world applications. Graduate students studied one area that could be very practical, could be "5-10 years" from being commercially viable, or something mostly theoretical.

My psychologist wife, however, didn't learn much practical as an undergrad and had to go to grad school in order to get a license in her chosen field - school psychology. So for her, it was kind a combo of both more focused and real world/practical.

I assume there's a lot of waste. Not all U.S. grocery stores are like this, and you can save a lot of money by avoiding the ones that are.

I hate walking across a giant store that's as long as two city blocks and has 4 brands and 30 flavors of everything but still manages to be sold out of the thing I actually want. It's definitely something that requires acclimation, and you can lose that acclimation if you don't visit one for a few years.

Something people haven't mentioned is you can also take advantage of cruise control to make your automatic downshift. Turn it on and then use the buttons to decrease the set speed and the car will downshift to help slow down. But this isn't something you'd do to normally come to a stop, more just on long descents to use some engine breaking.

My experience growing up in a rural area was that you could shop during the last hour before closing on different nights until you run into the manager who has to clear out the old produce etc. Make friends with that person and come back on the night they work, and they can probably get you good deals on whatever is about to be tossed. YMMV, and of course you have to be a bit of a night owl to make it work, but those were the best produce deals I've ever seen.
