Well, @eunoia seems to think so. I happen to disagree. But at least now we can discuss it without the emotional baggage of calling someone a thief. For whatever reason, people get worked up over that label more than "trespasser" or "squatter" or "moocher" ;)

I'm afraid we all might be wrong/right on some level. I.e.:

1. Getting into an area you don't have access to: Trespassing.

2. Tricking the security they have in place: Fraud.

3. Taking snacks from the lounge-area: Stealing.
