flush (or, how to gross out your co-workers)

ok, so i drink a lot of liquid during the day, so that means i go to pee a lot. the urinals in the men's room are the slightly old-fashioned type, in that you have to pull the handle when you're done; there's no little red eye that knows when you're through tapping a kidney and flushes for you. i've noticed that at least once a day, maybe more often than that, i'll go in and see that someone has used the urinal and not flushed. now, i know that since most urinals do this auto-flush thing, maybe people have been conditioned to not think about flushing so often, but i still really think that you could realize that you're leaving a stinky puddle of urine and give the handle just a little flick...
