To be completely honest, I would have rather found a job working with my hands then working at McDonalds. Secondly, I actually do that same thing at restaurants myself, lol.
From the first day, learned the the two tub method of bussing. One tub for uneaten food and trash(arghh those cracker wrappers were everywhere, especially if there was a baby, and don't get me started how many times I had to clean up baby puke) the other tub for dishes, glasses, and utensils.
