Im a heavy bartender tipper when out. Food service workers start at 20%. Its up to him/her to maintain. It doesn't take much either. Keep my glass full. Dont make me ask for a refill and make sure my order is right before you bring it out and def make sure u ask my wife what she wants first. Pretty basic stuff really but its amazing how many servers just dont give a shit. If u dont like ur job... quit! I dont want to feel ur shitty vibe. Ive had such shitty service I let it be known and walked out. I'm nobody but I expect a certain amount of ass kissed. Make me wanna come back cause of ur service.
