Smiling can get you out of a lot of things.
For example, the time I was told to stick a water glass and a can of pop up my butt when the resident got frustrated with me. Instead of ignoring him or being rude back, I smiled and said, "Well, I'll see what I can do about that. If you need anything else, let me know" and I left the room. He smiled at me before I left. I'm not sure if he thought he had scored a point or not, but at least he thought he was happy.
My few experiences with dealing with unreasonable residents have ended better if I stopped and smiled at them first. In the cases where I didn't, I failed at getting them to do what I needed them to do.
