Well, down here the police gladly go on these calls. I have had police escort customers demanding something ridiculous on a couple occasions. But if I call about vandalism or anything criminal, they don't even run the plates. They say "probably a drug sharing car" and say "see you tomorrow." The plates have matched the owner of record only about 10 times of the 100 or so we have dealt with over the years. In every single case, the owner has no idea where the vehicle is at that time. They like to see businesses choose the wrong path: There's usually money there for the prosecution, and its more fun than chasing the same 50 people with addictions to feed and mouths to pay around town all night.
All these are civil matters not criminal. Waste of police (taxpayer) resources if an upset customer brings along a police escort. If this were to happen to me, I'd be inclined to print out / have handy a no trespass order and insist the police witness me serving the customer and the next time the customer showed up call the police back to have them served with trespassing. Because once it's to that point you're not gonna see any business from that customer ever again.
That being said, I've had about one claim a year now - once due to machine malfunction, a couple more because of employee screw up (didn't secure a panel, came loose and fell against fender scratching paint; another time employee left an emitter out of the automatic
door control so the customer taking their sweet time at the undercarriage when
door couldn't see the eyes closed on vehicle and scratched paint).
In one instance I arranged to pay body shop directly. The other two instances the customer collected cash value. I figured it's their business whether they fix it or not, and if I don't have to pay for a rental car then I come out ahead. If I can keep a customer happy and avoid them bad mouthing me on google/facebook then it's all golden.
Oh I did have a customer threaten to take me to court - handle came loose while he was pre-scrubbing his car. Metal threaded handle gouged his roof. He wanted me to pay for it. I said I didn't feel responsible; it's a courtesy feature we don't charge for and that we expect customers to use good judgment, inspect for loose brushes, etc. Customer said he was sure a judge would disagree, promised to bad mouth my business in his social circles and that he'd see me in court. I waited a few hours, sent him another text reiterating that I didn't feel responsible but that I'd rather keep a customer rather than losing one and asked that he get three estimates and send them to me. Never heard from him so never had to pay out. I don't think I would have anyways (or I would have tried to compromise minimally).
For the damages that were above our deductible I didn't claim on insurance because I was afraid they'd just jack my rate up.
