Yes, one of my own preferred methods of supporting the Big Kit (eg, x-ray units) "out there" was to have it on contract with whomever was available, but do "first line" ourselves (myself). It was a win-win for all concerned. Instant response (by us), and far less to pay when a call-out was needed (at preferential rates).
And yes ... Christmas is just another day for me, Neil. I'm happy enough to plod on with the work (without interruption) whilst it’s nice and quiet. And I've got a fair amount to catch up on. But I have plenty of stuff like mince pies here. Plus tea, naturally. And I stay warm that way, as well! I've never really been what you might call "main stream" (as you know).

But as I've just
texted to a few folk:- "Peace on Earth, and Goodwill to All Men (and Dogs) - not just today, but
every day!" But, needless to say (and having just checked the World News), I won't be holding my breath on that one.
