A hobby of mine is to get annoyed at hand dryers. 80% of the models I find are eyerollingly useless. Blow a faint breeze for five seconds, stop and refuse to trigger again no matter how much you try to slap the air in front of it.
Then there are those 5% that actually gets it. Blowing a jet stream that makes the water droplets sublimate so fast you forget you even washed.
