Just like those stupid hand air driers at public facilities. God, how I hate those. Americans have it easy, in general paper towels are available even when the damn air thing is installed. But here in Europe, most often you only get the stupid air machine with no paper towels.
The high end ones take maybe 20s to dry your hands off. Properly drying your hands with paper towels takes at least as long and it wastes paper. What is your problem with an air dryer?

And the high-end ones, which are only marginally better, are very, very loud. Loud enough to trigger tinnitus in myself, for example.
Paper towels don't "waste" paper, they use paper (of which there's no shortage of, in the world) very efficiently. Plus in Germany and Portugal (at least) they have these reusable cloth towels that move between two spools.
If I don't have towels of any kind, I just wipe my hands on my clothes. It's not great but it sure beats the damn useless contraption.
