Patio Heating at it's Worst

I thought that we had hit a low with gas fired patio heaters, then some bright spark decided to make something even more convenient - electric patio heaters.

The worst thing is that now all of the pubs and restaurants are using them to heat their outdoor seating areas. I walked past a pub last night, the temperature was below freezing, the electric patio heaters were on and there was nobody sitting outside.
