Waiting... (2005) on Netflix

It's the dinner shift at Shenanigan's. Dan, the clueless boss, assigns Mitch, 22, a trainee, to Monty, the smooth talker who chases girls for one-night stands. Dean, a waiter, also 22, feels that life is passing him by. Dan offers him the assistant manager job and gives him until midnight to decide. Other waiters, cooks, and bus boys have their issues and personalities. Bishop, the dishwasher, is their counselor. During this shift, Monty may learn something, Dean makes his decision, Dan makes a play for the not-yet-18 hostess, customers get their comeuppance, the guys all play the in-house homophobic flashing game, the gals demonstrate why they won't, and Mitch gets the last word.
