By the time you get enough paper towel from the automatic paper towel dispenser in a public restroom, not only will your hands be dry enough from waving them in front of that stupid little red sensor, but you will also look like a complete idiot in the process. The same thing goes when you try to wash your hands only to hold them in the sink basin with nothing happening. I think I figured out why those things were invented. Check for secret cameras, because someone is watching you wave like an idiot in front of those things.
