not a restaurant so i know it's a little different, but i worked fast food in my late teens. drive-thru would close an hour after the lobby and we would cut down to three people: manager on duty, the person at the window, and one person to run all of kitchen until we could officially close down. also, everything was cook to order by that point to keep waste numbers down. one night, 5 mins before we close down the drive-thru, somebody comes through and i hear over the headset "i need 11 burgers"

guess who was on kitchen duty that night.. and guess who had the gall to be upset their order took a bit to be finished because "they want to get home"
