If it were anywhere but China, I’d suspect it was a set-up; I don’t know much – anything, really – about the Chinese sense of humour.
But you have to wonder:
a) How would the woman know that her car could pull a tow truck when the vehicle was already ‘on the hook’?
b) Why would the tow truck operator not have the parking brake set on his truck? Surely, that would be part of the Standard Operating Procedure.
OK, OK, so don’t over-analyze this.
It’s still funny.
