There's a way to avoid that "last drop" problem, Amos. What you have to do is stand there with your willy out and wait for about 15 to 20 minutes. The last drop will eventually evaporate. Problem solved.

You can, of course, speed up the process by blotting it out with some kleenex.

Or you can do what I do. Pack a battery-powered mini-hair dryer in a pack on your back. After having relieved yourself at the urinal you blot with kleenex, then blow off your willy vigorously with the hair dryer. This will result in the offending "last drop" being evaporated in jig time...figure considerably less than a minute. This is for men on the go, men whose time is valuable, men who cannot spare the delay of standing around for 15 to 20 minutes in a public (or private) washroom with their willy hanging out.
