Again, I would absolutely respect the wishes of the professor and take the time to do whatever s/he wanted. It’s just not something that I’ve personally encountered.
Perhaps it has something to do with my field and the institutions that I study at. Where I study/work, collaboration between researchers is valued above most else and there is very little in the way of hierarchy between students, researchers, and professors. We use first names and, to be honest, I rarely know the academic level of researchers that I’m on a team with until I see their credentials in print- (ie- professor, post-doc, grad student, etc).
We are all just products of our individual bubbles I suppose
