hand dryer propaganda

from http://www.straightdope.com/classics/a1_279.html:

Say what? I see their propoganda on every hand dryer I come across:

“To Serve you better – We have installed Pollution-Free Warm Air Hand Dryers to protect you from the hazards of disease which may be transmitted by towel litter. This quick sanitary method dries hands more thoroughly, prevents chapping, and keeps washrooms free of towel waste.”

You can even see it on the hand dryer pictures at http://www.worlddryer.com!!!

Why would Cecil say in 1981 that they don’t do that anymore?
