I am very friendly, and by bar is one of the most popular in my area. But as a bar owner, tipping is a pet peeve of mine. I understand being down on your luck, or not getting paid until friday, no problem. But there are some people that NEVER tip, and when I find out about it, I let them know that they are no longer welcome. Tipping is not a city in China.
I'm not disagreeing with you that good servers deserve tips - I don't mind 20%, 15 even for less than better service. I do take offense that because a tip is not as expected, the customer most often is the first to be "blamed".
BTW, how can someone conscienciously hire an employee for $2.15/hr and expect them to live on tips then bash a customer who's equally a tight-wad with money?
I thought you weren't supposed to tip the owner of a bar, just the employees.
