I think society as a whole has determined 18% gratuity to be appropriate. 20-25% is considered generous. However, I'm certainly not the spokesperson for the service industry. I'm just pointing out that in looking at it's tax policies, the IRS does not see tipping as voluntary. AFAIC, a far better way to deal with poor service is to complain to management and have the server reprimanded.
Exactly, also it might not be the server's fault -- understaffed or the kitchen not getting food out in a timely manner or other problems in running the restaurant that the manager can fix if he/she is alerted there is a problem.





DH and I often discuss this whole issue of tipping. We both regularly tip. However, there seems to be an underlying guilt associated with it. As in you're a bad person if you don't tip enough or at all. I said earlier in the thread, I think it's actually more beneficial to let the manager know if your server gave you wonderful service as well as leaving a nice tip. But I certainly don't want to feel like I'm being told to tip.
I have no interest in telling people how to live their lives and have no interest in being told how to live mine.
I'm glad it doesn't work that way here in Canada. I voluntarily claim a certain percentage of my total income from paychecks as tip income at the end of the year when I file my taxes and it works out nowhere near that kind of money. I know alot of waitressed that don't claim any tips.
