If saving 10c costs time worth more than that then it's not worth it. Ends there, really.

A friend used to work at a known cupcake chain in London and she literally threw out 30+ cupcakes a day. Whenever I was around, I'd try to convince her not to throw them but giving the box to some homeless or random passerby. Although that wasn't a common event given the boss.

So no, many places are stupidly wasteful, sometimes because of silly legislation.
