Its always Mr Yawn driving when I see them
It’s always my impression that Mr Yawn is doing all the driving, hogging the stepladder about, scurrying around doing DIY on the cheap, probably scurrying around trying to earn money on the quiet and generally acting as a prop for Yawn’s fictional successful business. I think he does what he’s told.
I know someone who lives very, very close by and she can’t work out where Yawn HQ is and thinks the thatch is operating under a pseudonym so that no one can work out the truth of ownership.
