I like using them because I don't have to touch the actual dispenser to get what I need. I imagine those things to be teeming with germs and bacteria. I've noticed that there are some people who go to restrooms and do not wash their hands after using the facilities. Instead, they head out of the cubicle, go to the paper towel dispenser and simply wipe their hands. Ewwwww! Gross!
There goes the slightly nutty in me.
So now, I'm pleased with the dispenser at work. All I have to do is wave and yay!
