No, you only know if someone didn’t DRY their hands. I wash my hands every time I go to the bathroom, but will go without any drying if all they have is those abominable air dryers.
Though one time I encountered a completely different type of dryer. I think it was made by Dyson (yes those vacuum cleaner weirdos). It looked different, so I said what the hey and tried it. It actually seemed to work, but I’ve yet to come across another. I suspect they must cost more than those awful ones that don’t work.
One of my favorite jokes from The Fella. I once printed out about ten ‘Press button–receive bacon’ stickers on a label maker and gave them to him to carry around in his wallet to put on dryers. Over the years, I think that was the best thing I ever gave him. (You know, besides the ‘adult’ things;) )
The Airblade does seem to work pretty well, and manages to not be obnoxiously loud.
Unfortunately a few years ago our workplace bathrooms were refitted with Excel hand dryers, which are absolutely deafening. I brought in an SPL meter a while back and measured the bathroom noise level at 96 dB when someone was using one of them. Paper towels are still available, but fuck, I can’t even stand to be in the room when someone else is using one of those dryers to blast water off of their hands.
Yeah, that’s what I want - the one size fits all heights model, wraparound design catches stray droplets, minimal/no floor space intrusion, anything that gets on the floor anyway just drains right in on top of the little blue cake thingy …
