What's the deal with guys who go in the stall to urinate?

This happened at work today. Im at the bathroom sink washing my hands. Nobody else in the bathroom. Guy walks in and instead of going to one of the three urinals like a normal person, goes into a stall, closes the door, and just takes a whiz in the terlit. These are definitely the people responsible for the pee all over the seat when you go in to take a dump.
