Dropping your pants all the way to your ankles is a maintenance issue...it sops up all of the errant piss.
I dunno about you guys, but I wear slacks just about every day of the work week, if I unbuckle, my slacks are going to fall down to my ankles....to combat this, I'll either have to widen my stance a ton (way past foot tapping close to the other stall) or have to hold up my pants while peeing. I'd rather just unzip, it's easier.
Unless you're wearing a belt, it's way faster and easier. With a belt 50/50. I don't like the hassle of navigating and threading through the narrow little underwear fly and then the pants fly as well.
First off, button fly jeans discussion needs to be merged into existing popped collar d-bag discussion. If you are offended by such a statement, your doucheness is cemented. Second, it is common knowledge that placing a hand or arm on the wall of the urinal before you prevents the pisser from accidentally falling in and making a mouthpiece of the urinal cake. Unfortunately, a side effect of said propping is looking like a douche. Last, and addressing the original question, pulling down one's pants in the public restroom should be avoided if at all possible (unless your intent is to meet a republican congressman, in which case - bombs away)
I had a teacher in high school that for some reason would never use the faculty bathroom. He would go into the students' bathroom, unzip, whip it out and put his hands on his waist and pee.
I just use the stall. That way I can get almost completely naked to do whatever business needs to be done...
