Yeah, I always linger a bit and assess the situation (if you know what I mean) before I head out to the garage. When in doubt, I hit the latrine. Better to leave a few minutes late then get caught with your pants down. Slightly different situation, but a friend of mine is a marathon runner. He never goes on a run without stuffing some toilet paper in his shorts. He doesn't think twice about copping a squat on the side of the road. He's probably a master at finding a good tree or bush.
