Hand-dryers in men's toilets are designed so as to blast droplets of incriminating-looking water down the front of your trousers. Except for those Dyson ones, which have a little trough of slime at the bottom containing at least one pubic hair and one bogey. Touch any part of that Dyson accidentally with your hand and you automatically die of a horrible infection, and always only breathe out when you're anywhere near one that's blowing. Hope this helps.
