Things in favor of Peyton here:

• Corporations in general
• There is no rule against it
• 7-11 has a pretty regular event where "fill a silly cup, feel free to be absurd" is a thing, so there is precedent
• That amount of soda is still probably profitable for the company, fountain soda is incredibly cheap
• This isn't regular consumption and clearly not a regular occurrence, if beverages were regularly freely available, it wouldn't be exciting to do this and this type of behavior would go away -- you have to hoard service when public service is an artificially limited quantity.
• This didn't deprive any other customer of soda -- the only downside here is a corporation losing a few cents of profit.

Things against Peyton:

• Hoarding is a bad mentality to be in (agreed with you here)
• It will take days to drink that much soda, and it will be flat and nasty

When poor people get a windfall of money, they tend to spend it all. It's why lottery winners tend to wind up broke. Because historically, money is a "use it or lose it" for those people. If you've been trained your whole life to adapt to things, it can be hard to do the right thing when those things no longer hold true.

Americans cant have decent public services because they abuse them... results in Americans desperate for public services... which results in Americans taking extra advantage of any public service that is available.... which results in a mindset that Americans abuse public services... which results in less funding... Its a vicious cycle.

Yeah I feel we have too adversarial of a mindset. Or maybe "too independent" like so independent that we don't even consider how we are all connected and only have a society because we work together.

It leads to people saying really silly phrases like "self made millionaire" which ignores all the people that gave that person money.

Like money is inherently social. You can't do anything with it on your own.

the mindset of Americans, as a fellow American, is "fuck you, got mine".

until we unlearn this behavior, we will continue to cannibalize each other. not sure how many generations thats going to take, but I hope it happens in my lifetime

This is not real. This is from a satire page.

This mentality is probably why Americans can't have decent public services.

What mentality? You mean falling for obviously fake bullshit that only idiots would believe? Yea, I'd agree that's the root of many of society's problems...
