A few months ago, our friendly (and I mean that sincerely in the case of ours) EHO popped in to do a spot check.

Whilst going through the place with a fine tooth comb, she pointed out a jet wash that was sat idly in the stock room.

"Do you have an RCD for that?"

"No."

"Why not?"

"It's petrol powered."

The rest of the visit didn't go quite as well!
