I recall our folk group being booked to play in a Kentish pub in the '80's which was on a rough estate. My wife was a teacher and spotted some of her excluded special needs kids in the pub, which wasn't the best start. Unfortunately the landlord had forgotten to unplug the fruit machine which was just in front and to one side of the band. Naturally enough, in the middle of one of our numbers some scrote decided that he would stand in front of our banjo player and spend the next half hour pulling the handle of the fruit machine. The landlord didn't dare intervene and looking at the specimen playing the fruit machine, we decided it was best just to carry on singing and playing. Quite amusing when we got paid as the landlord said he thought the gig had gone down well and would we like to come back? It's not often we declined a paid gig but we never did get back to that particular pub.
