Man: I'm selling blahblah, would you be interested?
Me: Uh, no, I'm a poor college student.
Man: Well, are you sure? Do you have any kind of water-filtration system?
Me: Um...I have a Brita filter.
Man: ::scoffs: That's such a chick thing.
And then he stalks off. Not horrible, but insulting my choice in water-filtration isn't really a good way to get me to buy something! And I'm not a chick. :'(
