I never go "Number 2" in public, mostly because of the toilet seats. That and I feel like someone's going to bust the door down and attack me, and I'd be in a bad position to defend myself. I somehow doubt it's possible to get an STD from them, though. But yeah, for the most part, I get my business done how I can. I've become more accustomed to going "Number 1" in a stall when there are no dividers between the urinals.
