There is a fine line between asking people to move and sounding rude.

Before i became acquainted with flyertalk, i didn't knew it was ok to ask for drinks/snacks as an AA EXP member on AA eagle.

I have had my fair share of self-important old men who comes and says "you finished with the pc or not?" when i have not even shut down the web browser.

I have also encountered numerous people who comes peeping into my computer screen when im typing personal emails. And when i tell them to back off, they say im not allowed, its a public space.

Public space = peeping into my personal emails?
