Here is a common scenario:

You order some food for pickup from a restaurant where parking is very tough. It's 8:30pm.

You get there and there is zero parking anywhere. However, next door is a parking lot of a dental office which has been closed for 3 hours. Nobody is in the lot.

You park there for 5 minutes to pick up your food, and leave.

You come back and find your car gone, and find out you owe $300 to get it out of a towing lot.

This is predatory bullshit and violates the spirit of towing laws, which were crafted in order to remove vehicles either creating a hazard or preventing rightful owners/users of parking spaces from parking.

This type of crap goes on all the time in Las Vegas and elsewhere.

You can get on your high horse and say, "I wouldn't park there because I'm not here to visit the dental office, so I have no right to be there", but that's crap. You know you would park there for 5 minutes if there was no other choice, and you know that you would be super pissed if you found the car towed by a company hiding while you did so.
