Just a Reminder to be Polite

TODAY,

I just sat on the main foyer (college lobby area) completely unaware that that area was reserved for green club event in our college. So as usual i started removing my laptop to start a quick work.

A female student came to me and told me to get up in a very rude way , just like i am someone who had apparently harassed her.

I didnt even saw her at the time when i was sitting.

If that space was reserved that was completely fine.

I wouldve moved after knowing it. But why cant people ask politely?

Although overall such instance apart from this has been polite for me.
