I've random workers from a restaurant nearby parking in my unused space (in a private enclosing) all the time. And my parking space even require a special card to use.

It would be nice if they offered to pay.

I reported them to the police, but I haven't heard about them fining them and they don't stop using it.

A neighbour used the parking space once and my landlord that was passing by reported her and she got a fine.

What I can't stand about the police here in UK is that it's so inconsistent.

Having a charger I get charged for would be an absolute nightmare.
