: For everyone out there who feels relieved once they've cursed the drive thru cashier out-------- not a good idea. You have to keep in mind that these are the people that handle your food.
Uh, how often do you encounter these alleged asshole customers? From what I've witnessed, they are far in the minority, unless your location is a joke. There are good ones and bad.
Regarding vindictive acts with peoples' food, I strongly advise you against pulling shit like that. You never know where surveillance cameras are lurking these days. And I wouldn't rule out a customer detecting what you did, either. And if that customer happens to be a 6' 5'' bodybuilder (who won't hesitate to take the matter into his own hands), I wouldn't want to be in your shoes, especially if you are 5' 10" like me, or shorter.
None.
