What do Brits do when they find their car has been clamped for illegal parking? Why, they pray for the swift action of Angle Grinder Man! (I gather a clamp over there is like when they put a "boot" on the tire of a car over here, meaning it cannot be moved.)
If only we had someone like that in this country, except he should go after crooked towing services! (Thanks to David Rutman for the tip.)
