i hate it when people take all the credit

i hate it when i bust my ass working than someone else takes the credit. that pisses me off. like at work, ill b busting my ass cleaning the store b4 it closes, while the other 2 ppl i was closing with, left to get some food, so i was alone working, washing dishes, sweep, washing the floor, putting everything away, everything. they come back when we're ready to punch out the next day the manager comes in and says wow, the superviser did a great job closing up. SHE DIDNT DO ANYTHING!!!!!
