WTF?

People are stupid.
I meet my friend for coffee. We sat in out picnic area next to her building.
While we were sitting there some woman walked between the bushes and sat next to me at our table and opened a book to read.

It’s a company area.
She does not work for our company
There are four table and the other three are empty!

Very creepy. We stopped talking and stared at her, but she just didn’t get it.
