This happened to me the other day. Soap all over my hands and the sink did nothing. I had to move around to try other sinks, moving around other people. Then some other dude goes to my last sink and it works just fine for him. I guess my hands don’t reflect IR light as much as his?

I’m glad I’m not the only one with this issue. Automatic hand dryers are even worse. Those Dyson V-shaped ones NEVER turn on for me no matter what kind of hand dance I try to perform for it.

Are you sure they aren’t the voice activated ones?
