When my daughter was a small child and she invariably had to 'go' while out in public I happily ask if she wanted her father to take her. After all, I told her that in men's rooms all of the toilets were plugged up, the sinks were broken and they smear poop on the walls... She would immediately start screaming.
But I have a warped sense of humor.
Oh yeah, if you don't have a piece of papertowel because of those useless blow dryers, use your purse strap. Do not touch the door handle.
