Some ways to limit your "involvement":
1. Never, EVER carry your regular wallet!! That is, at least take out your credit cards. My play wallet has an expired driver's license and expired and/or cancelled credit cards. I even have counterfeit "flash" money. "Flash" money works very well!!
2. Park AWAY from the hotel room, as appropriate, you're going to AND hide your keys behind a tire or find some other place to hide your keys. I've read where guys have had their cars taken too. Cover story? You were dropped off, your friend will be back in an hour. Good one for the fuzz if it goes in that direction too.
The good guys might take your car too.
3. Leave your high dollar cell phone in the car. BIG market for stolen phones out there. TMobile has the best long term pre paid plan out there. Notice I said, "long term". At least they did. If that requires explanation, PM me. Another argument for a "play phone".
4. Only bring the correct donation. If the ad says ANYTHING that suggests an upsell, don't even go. TIP. "Starting at" is a clue. Have the same attitude you should have with investments. If you can't afford to lose it, DON'T DO IT! No matter how hot her pictures are. Make do with a neighborhood skank!
That's enough.
