Actually, there IS a minimum wage for people who depend on tips, but it's extremely low. The last time I checked, and it's been a long time, it was about $2.13/hr. But most servers not only have to tip the bus workers and bar tenders, but there's a minimum percentage of their food and drink sales that they have to declare as income for tax purposes. Of course, if you make more than the minimum, you need to declare that.

Well, you could probably figure this out by my posts but I don't believe in a minimum wage either. People will work for what they can get. If someone is paying slave wages they won't keep help. That said, if we have to have one it should be for all, with tips being counted as added income. Most places around here pay minimum wage or better anyway. People aren't going to work for two dollars an hour regardless of how much they can get in tips.
