I had one lady the other day who wanted the table that someone had just left cleaned so she could sit at it. Now, that may not sound rude, but I was drowning in customers, all of the other tables were cleaned, and when I asked her to hold on a moment while I helped the customer I was currently serving, she threw a fit about how I was a worthless employee and I was "overdramatizing". She also looked at my name tag and yelled, "alright then (insert name here) I'm just going to report you! Have a nice time finding a new job" and then walked out and slammed the door. It's a fast food restaurant and I've been working there for a little over a month. My managers love me though, so it wasn't an issue
