When he came out, he argued with the tow truck guys a bunch, but they kept hooking up his car and arguing back and couldn't be reasoned with, etc etc. My friend sat on the hood to keep them from towing it. The tow truck operators threatened to call the cops, so my friend called the cops instead.
Before the police showed up, an SUV showed up with some tow truck heavies with, no doubt, plenty of illegal weapons on them, just to spectate and make sure things went the way they wanted.
Once the police showed up, the story changed a bit, and all of a sudden he could get his car unhooked for a "drop fee" that was 2x the minimum tow cost, I believe (memory hazy here). It was the law in Santa Clara County, but of course, the tow truck operators weren't going to volunteer this information.
Lesson learned. If someone's about hooking up your car, get in your car and drive away, unless it's in the air already. Don't even talk to the thugs.
