Incinerator demonstration!

The new incinerator at our allotment, which was put out of action by some silly people using it incorrectly, has been mended and today we were invited to a demonstration to see how to use it! 
As the chap who demonstrated said  the ones who did not turn up to the demo are the ones most likely to mess it up again.
However this time they have built a sort of fence around it and have much bolder notices and instructions plus it’s only going to able to be used for restricted hours on Thursday, Friday and Saturday am. As it is very near a cricket pitch it can not be used on Saturday afternoons or Sundays when matches are taking place and the wind may blow smoke over the pitch!
