Getting tipped out, do you think im getting ripped off?

To me this is a no brainer, but Im going to ask opinions anyway. I work at Tilted Kilt and my job is to buss tables after the customers leave, but Im such a hard worker I always end up prebussing these girls tables everyday to the point of working like a robot with perfect timing for each server not having to even bring back there plates to the dish area. I make 8.75 a hour with no tip share. If im prebussing everything I think I should get tips, what do you think???
