Where did tipping come from and how did we let this happen. Imagine if this is how our government or baseball players were paid? Why is your service job deemed so unimportant that random people can judge you and decide your pay, some of these people who have never worked a day in their life. These business get away with hardly paying taxes and giving the employees the rights they deserve.
I've had bad service from other businesses and paid full. If the food sucks you should get free food , not take money out of the servers pocket by giving less.

I propose we get rid of the 10-20% standard and tip per drink and plate. A beer at my bar next door cost 1.50$ but if I go to a club downtown it cost 10.00$ . Why would the service charge change?
