guess in my opinion there is only one place number 1 and number 2 should be done and that's in a toilet in the bathroom.
it's ridiculous that guys will go to the extent of peeing in a public place just to safe money and time from stopping at a restroom. we are grown men, we are talking about 1 or 2 stops in an 8-10 hour work day. if your going more than that or can't hold your bladder that long then go see a doctor.
I even pull an enclosed trailer where I would never have to stop but I only use the enclosed in a real emergency.
guess I'm weird that money doesn't mean so much to me that I'm willing to pee in clients bushes just to save a few bucks.
