how to handle snooty people ...

give them a twisted, sharp and nochalant comment. this will stop them on their tracks and they will surely rack their brains out in trying to figure what the heck do you mean. at least you get them thinking - either they get the irony of what you mean (hurray!) or they would get even more snootier. in whichever case, just act as if you don't care and continue minding your own business.
