Thankfully I have physical knobs on my stovetop, so my current least favorite is my dishwasher. When am I practically guaranteed to have damp hands? After doing the dishes. When do I need to start the dishwasher? After doing the dishes. Why have an interface that requires dry (but not too dry!) fingertips?

The extra knife twist is that if I misjudge how wet my hands are, I get a little water on the dishwasher controls and then they don't work at all until I dry them thoroughly.
