This is not related to nursing at all, because I am not a nurse yet, but it reminded me of a funny story. I used to serve and bartend, and some people just can't help but be nasty to people. I don't even think they try. It's just the way they are. It's like they are the only people in the world who matter.
I had this one guy one time who came in and he was a weirdo, I could just tell. He ordered a Ribeye med rare with no side. Instead he wanted a soup AND a salad. Wow, this was 4 years ago and I still remember.....anyway, he wanted his soup and his salad at the same time....okay weird, but I'll oblige. So I brought out his salad and soup out asked him if he needed anything (of course he wanted crackers) and told him to enjoy and I'd be right back. When I came back the man says "Miss, my soup is too hot" I smile and say "Sir why don't you eat your salad first and let the soup cool down?" I MEAN HE HAD THEM AT THE SAME TIME COME ON!! Well, he smiled at me and I said his ribeye would be right out. Before it is even done, he has flagged down another server and told her that I never check on him and he didn't want me as his waitress anymore! HAHAHAHA! The other server was ****** because she had to wait on him then. I didn't even care. I just walked by and smiled. I think he wanted it to bother me.
P.S. He also had to pick up 3 silverware rolls from the front. Don't ask me why he needed 3 silverware rolls. He also grabbed a stack of beverage napkins on the way to the table, and he wanted two drinks. There were probably 5 tables in the whole restaurant. I think I could manage to refill his drink before it ran out. I was a darn good server if I do say so myself
Like the others said, just smile as you walk by and don't let it bother you. Some people are just high maintenance, without caring about inconveniencing others.
