I take the opposite point of view, I don't like being around people that are too sensitive or takes an issue with everything. Or gets their feelings hurt over small things. Saracasm/Jesting is a great way to force them to reveal themselves early on. Getting to know people like that is a waste of time for me and them. I will just hurt their feelings, and they will just annoy me with their suckage. Better to just figure out who's who early on.
