As a waitress, I am required to tip out other wait staff and the bartenders. This is a substantial amount of the tips earned. Can, and where, can I deduct expenses?

I am required to pay credit card processing fees when a customer uses a credit card.  Additionally I have to tip out bartenders at 6% of all alcohol sales and 3% on all food sales to servers and support staff.  Where can I show these deductions from my total wages?
