On the roof

Today I walked down to the new workshop of the guys who look after Lofty the camper in the hope of getting a blip of him undergoing surgery. I'm told that he's now motoring sweetly on petrol so hopefully no more running on reserve with fingers crossed while trying to reach an LPG station.
However, unfortunately he was elsewhere for some 'orthopedic' surgery so no blip.
However, on the walk back home this guy on the roof appealed.
