Great flash, and so true.
I hate those damn crowders at the urinals, the blowing hand dryers, and the push-button sinks! One suggestion, I think you should have said something about how people never wash their hands before opening the door, and how in some places the door handle never gets cleaned. I've seen tons of door handles with all kinds of mold growing on them... And with no paper towels there, you've either gotta use your shirt, just stick your hand on that mess, or wait until someone else comes in so you can escape. Damn unsanitary bastards...
Keep up the great work, I hope to see more flash from you in the future!
