Input: Alright, so, I've been working as a Dishwasher for just under a month at a small, locally owned restaurant. I'm assigned to work with this other guy who's been working there for about two years. He knows I'm new, but let me clarify I'm new, but not stupid. This is a really simple job that involves running dishes through a dishwasher, occasionally scrubbing, putting dishes away, mopping, and sometimes helping bus tables. I was capable by day three. It's really simple. My Co-Wrker loudly complains that we're going to get out very late tonight. (Closing time is 10:00, but dishes don't usually get out until 10:30, because we have to wait for all customers to be out, so the cooks can stop cooking, so they can give us their dishes.) 

He keeps complaining, and the night manager and him are friends outside of work, and they both are standing five feet away from me, whining how much they hate 'newbies'. (They never mention me, or my name, but it's pretty heavily implied.) I'm getting really annoyed. At about 10:00, after 6 hours of listening to him complain, I decide I'm going to go as slow as possible, ask every dumb question,  and  make so many mistakes, we're going to be here way late. If he wants to complain about me being slow, I'll give him something to complain about. 

We eventually wind up clocking out at 12:14, (Almost 2 hours after we usually would) and my Co-Worker informed me that I ruined his plans after work with his friends. I give him an 'innocent' shrug, smile and say, "Sorry, I guess I'm still learning." 

AITA? Or was that just the right amount of revenge?
