YTA Some bars and restaurants have tip out systems, if they have bus boys, cooks, etc. Tip out systems are essentially when the servers and bartenders give a certain percent of their tips to bus boys and cooks. Some restaurants have the bartenders tip out 1-5% of their total sales. So since the total sales will be really high after selling a $600 shot of bourbon, he would have to tip out a lot more. So if he tips out 5% for that shot, that means he tips out $30. So you’re screwing him over because he’s tipping out more than he even made, because you went well below 20%. He should have hypothetically got 20%, tipped out 5%, and been left with 15%, instead of being negative at the end of the night.
