They certainly can be stupid. Here's a good example. A guy came up to my son (where he works) complaining that the faucets in the men's room don't work, and he needed some hand sanitizer, because he had to rinse the soap off his hands in a toilet (the bowl, not the tank).
The faucets are motion-activated. He's had to have seen something like that before in his life, or he could have asked.

If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
