yes. be nice, or leave. if you notice, i am not using exclamation mark, indeed, just a FULL stop. in this world, not everyone is nice or good to you.
so why are we angry with them, got emotional, and risking our health from having higher blood pressure? the best way to manage unreasonable people, is just dismiss them. their main intention is just to be a jerk and see how you react to them. the more you react, the more excited they are.
so, in the future, when you have these jerks being unreasonable, you should just smile and say: ” be nice, or leave” 🙂
