He's a Pisser

Yesterday, on my way out the door I stopped off in the bathroom as I normally do. I used the urinal next to someone who was on the cell phone. I think he was speaking to a voicemail because he said "Did you just call me? I'm indisposed at the moment, I'm, uh, I'm, uh, I'm in the restroom. I'm leaving now so if you need me call back in a few minutes."
Then he looked at me and said "You can never stop working."
I laughed and said "I'm never going to borrow your cellphone."
He said "Well, I didn't want her to hear the splashing and wonder where I was."

This is not the same person as the blatant pooper.
