clap when a plane lands
dont say thanks when you hold a door open
get to the till without deciding what they want yet from the menu while you stand behind desperate to order
quote a post and then say "haha +k" when what they really mean to say is "im jealous of your post:karma ratio and if I give you some k can you give me some back please?"
post viral facebook status updates
have ski poles shorter than their t-shirts (when did that happen?!)
are herbivore and bitch to omnivores about their meat habit. go away
take ages at the ATM
let their kids run around screaming in restaurants
