Just a quick piss, I use a urinal. Not for the peek factor, just cause it's easy.
Except at work. I use a stall. And everyone know that when I'm in there...SHUT THE FUCK UP. No chat, no jokes, Just piss and go. Thank you.
My boss is the opposite. The bathroom is a social club. (Except with me. He knows). If the ceo comes in when my boss is there, he turns on his heels and walks away.
