"Is there a socket anywhere?" asked McColleague.
"Yes, at the other end of the building. We could make a hole in the ceiling in the tea room stores, and thread a lead through the roof space."
Lovely Warden arrived with an extension lead.
"Up you go, Sam," said my Boss.
("Sam" is not Lovely Warden's name. My Boss calls all men "Sam" and all women "Gert". It saves him from having to remember too many names.)

I watched in trepidation as Lovely Warden stepped up onto a swivel chair, wedged in amongst the junk, balanced on a plank of wood on top of a step, and then progressed up a pile of rather flimsy-looking boxes, before wriggling through the small gap into the roof space.
Much tapping, and knocking ensued, as Lovely Warden and the Boss married up the end of the lead with a hole in the ceiling.
He emerged, backwards, some time later, lead in hand, covered in cobwebs and grime.
"Coming back out was the hardest part," he said. "I couldn't see my feet. It's hard enough when there's a ladder, but with just boxes and a swivel chair..."
McColleague and I nodded. We had seen just how tricky it was. I had only managed to capture one image without camera shake, due to laughing so much.
"Well, at least you're down safely! No more health and safety concerns for us."
"Here, Sam," said the Boss, fiddling with the plug he was attempting to reconnect to the lead hanging from the hole in the ceiling, "you'd better check this. I can't see a bloody thing."
I gave McColleague the look that means "get ready to dislodge him with a broom handle, should this go horribly wrong".
There was no big shock, no sparks, however, just a satisfying thrum of a functioning chest freezer. Hurrah. Now we can store more bread rolls than ever before! Worth every exciting moment, I'm sure you'll agree.
