what occupation people sometimes get angry at?

sometimes doctor make me very angry.one time, one of my friends and I went to a hospital and wating for therapy.but some doctors do not pay attation to us any more, so everytime when saw their face, I really want to push them.you know? in our country, sometimes the doctors are called "the wolf with white overcoat"

Customer service when they don't really know how to handle it. It pisses me off that they try to appease the person but you know that they are just pulling your leg. Also salespeople in stores. Those type that when you ask for something, they actually just give you a blank stare.. or worse, tell you they "don't know". Sheesh!

I sometimes get angry at carpenters, electricians, plummers etc that do not do a good job. Sloppy people make me mad. I also get irritated at people working for the government, insurance companies etc that make things much harder than they need to be, and use far more time than acceptable. Rude people at customers service are some other folks I do not like much.

the service industry receives the most complaints. like rude shop assistants, some of them i really should say idiots. because they don't realize who they are when selling expensive goods, they are quite snobbish as if they are all millionaires, forget about who they actually are.
