Stand up for yourself & don't let people walk all over you. I know I did the best I could do & was complimented many times on the meals that I did make for the private patrons & guest. When something isn't going right stop right then & there & make it a point to talk with management asap. They would have a greater knowledge of what kind of kitchen manager was doing & what she wasn't doing so that would have made your job a lot easier to do instead of you doing triple duty.
