The type of person who drives straight into your workshop is also the type who hangs around, trying to 'help' and get extra stuff 'just quickly' done for free.

We had a guy drive his car into our workshop and claim that the wind blew a roofrack onto the side of his car (it was leaning up against a wall for some days prior) I reckon he stepped on the leg causing it to fall. Anyway, long story short, he complained, boss (softcock) caved in and paid for the repairs on his car.
