Did you know.... There's actually an etiquette to going to fast food places and restaurants? A lot of people don't know this, which is surprising. One rule of thumb when going out to eat, it is considered very impolite and extremely rude when large groups or someone with a large order to come in less than thirty minutes before they're about to close? The workers are exhausted after a long day of physical labor, standing over a hot grill, and dealing with nice and not so nice people, and they just want to go home like everyone else.
So please, next time you wanna get food from somewhere, think about the workers first. It's not the end of the world if you have to end up cooking for yourself tonight. :)
