No, he’s weird. Taking a leak in a toilet isn’t going to block anybody very long, and in your case there were two more spare toilets anyway.
Along those lines, I have seen men using a toilet stall to pee, as you did… and closing the door behind them. Why?
I tested this with a squirt gun, some food dye, and a broken urinal. Fluid already in the urinal will not splash back on you.
A urinal uses a lot less water. Maybe he’s just environmentally conscious. I will do the same unless I REALLY gotta go.
Not-flushing uses the least water.
True, and I often don’t flush at a urinal, depending.
I’m sure that eventually I’m going to shart pretty badly one of these days, while trying to maximize my fart volume while some dumbass is chatting away while taking a crap in our work bathroom.
And we have one of the paper-towel-penis holder types in our office- I always want to ask him what he’s doing that his dong is so unsanitary that he won’t touch it, but haven’t had the balls to ask yet, seeing as he’s a cranky, awkward old-ish guy. I suppose maybe the logical answer may be that he takes the paper towel, pees, and uses the towel to hit the flush lever because he thinks it’s germy. (which it’s likely not; metal surfaces are typically toxic to bacteria)
I’m a guy, but I’ll cop to doing this. I’m not sure exactly why. Maybe I just like wasting water. 
Actually, DrDeth, thanks for your theory. That actually makes sense, and it would never have occurred to me.
Another weird behavior are those who record videos of a toilet flushing and post them on YouTube.
In most public restrooms, the stall doors hang open just a few inches when the door’s not shut. So if someone’s in there but hasn’t shut the door, you don’t notice until you push the stall door the rest of the way open to go in, and it bumps off of the person inside.
So that’s why one should close the stall door, regardless of whether one is peeing or pooping inside.
I would just ignore that, unless you notice him holding it in a paper towel tube.
I always wash my hands before urinating if I’ve shaken hands with or handled something from a person with a visible cold sore. It’s just not a chance I’m prepared to take.
This would also make sense if you’ve been eating extremely hot chicken wings.
At my work there are 3 stalls in the bathroom. As far as i can tell, they are identical stalls. If I have to crap, I’ll go to the one farthest away. Almost invariably, if someone else comes in while I’m in there, and goes to a stall, it will be middle stall, next to me. What. the. hell.
Because I don’t like standing there with my wang out. I’m an introverted, overly modest person and I hate public bathrooms. I get nervous. If I think there are enough open stalls that someone with a shit emergency will be alright, I’ll use one. If there’s a door, I might as well use that too.
If there is a shortage of toilets, I’ll use the urinal, but pissing against a wall just isn’t my idea of a good time.
The ice in the urinals thing is because the cold will tend to suppress smells.
A couple of buildings back in my current career, there was a handicapped stall in the bathroom that I liked to use. Weirdly, every couple of days there would be a big, wadded paper towel in the middle of the floor, soaking wet…and as best I could tell without inspecting it, it was perfectly clean. I still have no idea what was up with that.
Probably the weirdest public bathroom habits I can think of is that the handicapped toilet in the men’s room on my floor is by far the most popular place to take a crap versus the normal stall adjacent to it.
I don’t get it- our handicapped stall is like a jail crapper- it feels like it’s out in the middle of a huge stall, and I don’t like it.
Probably a legitimately disabled individual driven to desperation and attempting to make the stall a bit less attractive to all those who don’t need it.
Or, you could just leave the door wide open, leaving your back exposed the way it is at a urinal. You don’t have problems with people trying to get in to your urinal stall, do you?
That does it! Now I’m going to go and park in a handicapped spot!
Actually, I’m sure we could start a whole new thread on this, but I spent 10 years in that building and never saw a handicapped male! Ah, the classics…
Or just handling jalapenos.
