Not today specifically, but just in general. It really annoys the ever-living crap out of me when guys, in the men's room, use the urinal and don't flush. It baffles me how you could be such an inconsiderate prick.
About the only sensible reason I've ever been able to theorize in my mind is they think they are doing it to conserve water.... but that is the whole reason urinals exist in the first place. They are so that guys can use them when they are just there to pee and the flush uses much less water. Truth be told, though, I don't think that is even why they do it anyway. I think they are just inconsiderate and rude. I shouldn't have to come into the men's room and see your business.
