I'm going to tell someone to shut up
That feels rude. Why do you need to tell them to shut up?
You always keep on talking and you don't hear me.
It's mean to tell people to shut up. You should be nicer to others.
Fine, I'll call my manager.
If you want me to listen, then I am here to do so. I do not think it was nice of you to call your manager nor tell me to shut up, as it is very mean and you're unnecessarily involving your manager in this situation. It is best to just be nice and act politely to people moving forward.
