Sorry to hear about that. Is this a popular club? The kind that attracts high-end, up-scale customers? Sounds like it since the employee drives a BMW. If it is, the owner would be very protective of that image and would not like any bad press. So, here's a thought; go the legal route but with a touch of Don Corleone.
- View the tape with the manager. Don't say anything - let him/her do all the talking.
- After you have viewed the tape let the GM tell you what he/she is going to do.
- If you like what you hear, then let it go, but make a deal that you don't have to pay to get into the club for a year.
- If you don't like what you hear, then ask if that is their final decision, then leave.
- Then launch the "bad press" campaign, write to the local paper(s) about the uncontrolled vandalism on the rise at the club, and that employees even vandalising the customer's cars. Don't mention your situation specifically. Be as anonymous as possible.
Before you send in the letter, stop by the police station. Find out if any prior reports have been filed against the club. I'm sure you're not the first to have this done to you. Incorporate the history of vandalism in your letter. Also, in your letter, ask a question of the readers: If the employees are free to vandalize parked cars, what are they doing to your drinks/food?

Just a thought .........
