Wipe hands on pants

Hand dryers in public restrooms have finally improved the point when they blow dust off a counter top. Back in the eighties when I first remember their appearance, the dryers the public toilets were ridiculous. For the last 30 years, hand dryers have been largely wishful thinking that "environmentalists" used because they were supposed to save paper. After washing your hands, there was always a dilemma. The air flow was so weak that not long after you put your hands underneath, you would feel silly and embarrassed to have people witness you engaging in such a pointless activity. Subconsciously, you knew that the dryers were not going to get next guy's hands warm, either, but his impatience drilled into the back of your head filling the air with unspoken thoughts like, "Come on, man. I got places to go!" So you'd step away with your wet hands in order to give the man a chance for the whole pointless dance to start again.
Now, the air flow of many of the dryers I have used lately—in the new shopping malls and some airports—is strong enough to inspire satisfaction. It still takes more time than you want to spend in the bathroom, but things are happening; and it's a pleasure to have my hands warmed.
I used to be that all the hand dryers had the manufacturer's name—World Dryer from Berkeley, Illinois. (I was at least a little pleased that something I used was NOT made in China.) They had a metal plate fastened to them. On this plate were the directions: 1. Push button 2. Rub hands under warm air. 3. Stops automatically. After a week or so in the toilet—I reckon it happened that fast because every, literally every, machine I saw had some of the words or letters scratched out by some vandal. Many of them had the typical: "1. Push button 2. rub hands under warm.". One of them has stayed with me all these years. After the 3 directions with all the customary alterations, was scribbled this: "4. Wipe hands on pants." It was perfect.
