I'm a little blunt to work at a fast food place, really. haha, I've heard stories of moronic customers, and my responses wouldn't exactly be 'nice', hahahah.
You need a certin qualitly to work in this world lol. I don't seem to have to many complaints where I'm at now, if there is one its usually something stupid like a crumb on a table. No joke. Sometimes I find it really hard not to bitch slap some idiot for the things they say. I remember a customer made one of my friends cry all because she asked him if he would like to add a pastry item for 99 cents. Aparently this dude had a stick so far up his ass, cause he flipped out over that question. Thats the kinda bullshit you gotta put up with. Wish I could get out of it, but for now its all I know.
