I have a job as a night auditor making minium wage. It is starting to suck.?

I have to wash the windows, mop the floors, do the dishes, vacuum the floor along with checking people out and doing the night audit. My last draw was tonight. I came in to work and the dishes was left for me that was messed up on the morning shift. The second shift girl did nothing. She said she was told by the owner I should do the dishes left over from this morning. I got off at 7:30 breakfast last until ten. I am looking for me another job. I am tired of this. I make 8 dollars an hour, its not worth it. Do anyone feel I am wrong?
