Some places here already tip share... I know the Ruby Tuesday my ex-wife used to work at did it. I thought the concept was ridiculous then too... It basically made the bad employees worse and the good employees not care to continue being good. A percentage of the tip pool went to pay the busboys too.
While on the tipping subject... I tip well for reasonably good service, but have made an example out of very poor service before as well. I've never worked in the food service industry and was always told by those who had (who all tipped well no matter the service) I just didn't understand and all service deserved a fair tip. I also struggle to understand restaurants who do nothing more than quickly bring your food after ordering that have a tip amount on receipts... I don't recall ever leaving a tip to pay for service that hasn't been rendered yet. I may be the only person that thinks that way, but I'm don't feel it's necessary to leave a tip for someone only delivering my food.
One last thing as it seems to be a solid division among people who tip... Do you make your tip an even dollar amount or the total an even dollar amount? I always make the total even as I'm OCD and it makes more sense to me, but have been told that's rude to give the server an odd dollar amount as they don't want to sit there making change at the end of the day.
