The company I was working for at the time was fairly large and after the incident I had plenty of opportunities to re-tell the story. It happened as I said it did but I glossed over the fact that I spent the night in jail (not fun) and narrowly escaped prison/probation (the judge sympathized with me - the security guard had several citations against him for physically confronting other people). The only reason why I wasn't bankrupted was due to my company agreeing with me that I was performing my job (up to the assault) and supplied the lawyer.

I use the story now as a funny anecdote in don't-get-caught-like-this sorts of training sessions.
