Sounds familiar
Probably mentioned at some time before that I used to run a bank of autoclaves in a previous tech role. The machines we had were all compact ones, about the size and weight of a large microwave (the big heavy 80s ones).
Turned out no-one had ever enquired about their servicing, which is always wise when dealing with a steam-filled pressure vessel....
Anyways, we contacted the phone number on the machine and the supplier offered to send out their service tech to give the autoclaves a service and inspection to be sure they were safe. This guy turns up, I show him in. He begins taking the autoclaves apart, then turns to me and asks "Where are the parts?"
"What parts?" I reply.
"The parcel of parts you should have had delivered."
"First I've heard of this, was the parcel sent under your name?"
"No, don't know who it would be sent to."
I called up the supplier and they had just sent the box in the post with our company name and address on, with no FAO. Up until this point they hadn't informed us that the parts would be arriving separately without any tracking number. During this phonecall the service engineer meanwhile decides to continue disassembling the autoclaves and promptly drops one on the floor. At that point I had more than enough and chucked him out, although I think I exercised considerable self-restraint in not grabbing him by the collar!
This made the supplier, who it turns out were just a glorified sales house, panic.
They had contact details for the UK distributor of the autoclaves, who were based in Swansea (we were in east anglia, so on a good day a 3hr+ drive). Their service engineer jumped straight in his van (which was stocked with all the parts needed to fix these autoclaves and more) and called me from the M4 motorway with a promise that he'd be there at 9 the next morning, having booked a local hotel last minute. I very much hope he got paid a decent bung for that!
