MQ in secret helicopter base in Shropshire. It was "spend some spare dosh in quarters" time of year, so a plumber came around to plumb in fittings for washing machine in unfeasible large downstairs loo.
Very welcome, but pointed out to plumber there was no socket in loo; couldn't use extension lead to hall in case loo needed for its "primary duty".
"Don't worry mate," says plumber, "they thought of that, there's another bloke coming round tomorrow."
So that would be the electrician methinks. WRONG! It was a carpenter to cut a (fairly) neat triangle from the bottom of the door, so you could shut it while using the (not a stores item Sir) extension lead!
