The owner today at job[1] pulled me aside today to tell me that I'm doing a poor job waiting tables, listing several things that I need to "start doing," like being unafraid of people, smiling, putting ketchup, mustard, and silverware on tables, and other things that I apparently don't do. Because of this, I've been demoted back to training. The customers tell me I do a great job, tip well, and I have yet to have someone ask me for silverware. Any way to tell the owner I disagree with her, without getting fired?
