The problem is, every American thinks they are every other American's boss at every juncture, and if they are dissatisfied they will push as hard as they can to get their fellow American fired on the spot.
When I tended bar and managed a restaurant during grad school, I probably dodged getting fired a dozen times. People suck. One guy threw a punch at me as I was "escorting" his drunk arse out the door. I pushed him and ducked.... he broke his hand on the door. He sued the company and attempted to get me fired. Neither outcome worked out well for him, but it wasn't for lack of effort, let me tell you. He even offered to drop the lawsuit against the company, if they would fire me. They did neither, and he glared at me every weekend he came in....... lol.
The best: I had a guy ask me to fire his server on the spot, who he knew (and told me) was "in the weeds" and extremely busy, for not bringing him his refill. When I pointed out, there was a full beer in front of him, he looked at it like we had Star Trek transported it there. I had watched his server put the drink on the table, while he glared at her, as she served the other guests. Then he motioned for me.... LOL.
