standards... that's all we have

Why can't people be bothered to put away their cell phones when buying something at my store? Why can't they take turn off thier ipods/cd players and listen when I'm talking instead of pointing to their ears and giving me the "oh sorry I didn't hear you" bit? Why have manners just gone straight down the toilet? I will get women talking to their cell phones as loud as anything so that everyone can hear them and we will complete an entire transaction and they wouldn't have looked up at me or said a single word to me the entire time. That's soooo rude! I have this one kid who comes in almost daily for Oreo's and he has yet to say one word to me in the 2+ years I have been waiting on him. He's always got his ipod running and can't be bothered to say hello or thank you. Bastard. I don't walk around blabbing all day on my cell but if by some chance I do have someone on the line, I always hang up and call them back when it's more convenient. I try not to use it in my car if at all possible so I don't crash in to the driver in front of me because I am too busy looking at my phone and not the road.
On the other hand I don't like it when people are too overly friendly. If someone is nothing but smiles and praise for a pack of gum then you gotta know they are up to something. I have one customer who says thank you after everything I tell her. She's so positive and friendly and cheery all the damn time you just want to shake her. I'm sure she follows the philophy 'get back what you put out' but good grief she takes it too far. I don't trust the overly friendly, just a thing I have.
Then there are those girls who wear flip-flops that don't pick up their feet when they walk and their shoes smack the bottom of their feet. Oh my god that annoys the holy fuck out of me. That's more of a pet peev than a bad manners thing but I thought since I was unloading I'd throw that in.
