Ha! I used to have this problem real bad, and developed a method for dealing with it that probably works just like the multiplication method. As soon as I unzip at the stall, I start tabulating how I would spend a million dollars if I had it. I keep a mental log of the balance while the pee flow starts, and once I get a good stream going, can relax my mind and finish regardless of who walks in or stands next to me. The worst situation is at a concert or sporting event when there is a line BEHIND you! My million dollars doesn't work well there.
