I don't mouth off to airline people or people who handle food I'm going to eat...its not worth it.
I never get testy with food service handlers. My hubby got testy with a worker at a Taco Bell here in town. I took my little girl and left him standing at the counter. He followed me and asked me why I was mad. I told him because there was no way I was going to eat at a place where the employees were angry at a customer.....they may spit in your food. Having a couple of hard shelled tacos and a steak gordita wasn't worth it.
