It depends on where you work for those tips. Fine dining and busy bars tend to do good. Though I was a bartender at one somewhat busy bar and tips were shit because the clientele were just that way. Old folks and people who spent all their money gambling on video poker mostly. Was kind of annoying when someone won big and bought the house a round but didn't tip at all or tipped $1.
But I only had that job for one year before I left to work in IT. No tips but way better pay overall.
