As a part time job , I have been trained in the art of vehicle immobilisation, this is a nice little earner >>> so to speak >>>>I am always smart and very polite when dealing with these law breakers who park illegally, and explain to them the error of their ways as they pay me the release fee . Why is it no one ever thanks me or even smiles while I am providing this service ? in fact some of my victims SORRY ...clients can be down right nasty ????
