Great advice. Another variation on that is just getting them to look something up for you that is at least tangentially related to your work. Anything where they are now helping you changes the power dynamic and will make them super uncomfortable.

A good project manager will be confident in their position and in doing whatever they can to help the project and won't mind. But that type of person wouldn't be looking over your shoulder unless invited.

oh that’s fantastic! keeping this in my back pocket

Heh. Fortunately, I don't work there anymore.
