So the question, if you're in public like this, do you trust the other people around with your personal belongings? If you leave your coffee unattended, do you come back and drink it? Are you paranoid about what could have happened to your stuff while you were gone, and wonder whether it will be there when you come back? As the person sitting in the next chair, was I supposed to be watching it for him, even though I wasn't asked?
It just amazes me when I see this stuff happen, because I have sort of been conditioned to trust no one I don't know. I always take all of my belongings with me when I leave my table, even if I'm planning to come right back.
How about you?
