I know we're supposed to do things for people out of the kindness of Our Own Heart but nothing irks me more than people who are ungrateful. One of my co-workers needed to be off last night because he had a death in the family so I was asked to cover his shift. Bear in mind this was in addition to my shift so in all I was at work for about 14 hours. When I came in to relieve him this evening he was talking smack about I didn't put up a few pans and a few utensils. So I went to management and I said don't ever ask me again to cover another one of his shift because I'm not going to do it
