Ugh, my job SUCKS.

Show more cleavage -- it seems to work for the ladies.

Really though, I don't know where you work, but most people I know don't screw people out of a tip unless they're ****ing up in the first place. Most people tip between 10-15% from what I've observed (I personally tip 15% minimum because it's easy to calculate and it's usually reasonable, and 20% if they exceeded expectations). If you're only getting 9 bucks tip cumulatively, are you doing a good job at work or are you slow/screwing up something often/being rude to customers/whatever?

If the fault lies in a cheap customer base for some reason, find a different job -- you should be earning more than that if you're doing your job well.
