Yep, disrespectful and rude too, which causes annoyance.
I think your experiences with that boss have given you a good bad-listener-radar and isn't it funny that sometimes people like that manage to work themselves into higher/management positions. It never makes sense.
Well, it seems he is a good listener and leader when his boss is around. I guess it is also being able to surround himself with good workers that help them get into higher positions. With management, I feel like it is how you deal with people instead of doing the actual work most of the time.
Management, (leadership) is exactly about dealing with, and getting the most from, people. ✅
