Back in the days I was doing frontline support, one of the clients was a big investment co, and we had all kinds of strange commitments supporting the big wheel anywhere in the world. I usually dealt with him, and he was generally polite and reasonable.
One Thursday afternoon, he called up just before closing time, from his villa by lake Como. (When I say by, I mean with private shoreline and jetty. V nice.) His pc wouldn't turn on. I did the usual basic troubleshooting - "are you absolutely sure it's plugged in?" - but there wasn't anything I could do remotely. I passed him to the manager who would normally deal with sending out engineers, and they tried to get him to send the machine to us to look at. Cue shoutyman.
The client insisted that they send an engineer asap, and insisted it was me. Manager explained that I don't do work travel because I won't go without my partner. My partner worked on the same desk, which the client knew. Shoutyman really goes off on one, so we can hear his voice coming out of the handset from across the room. "I DON'T CARE ABOUT THAT SEND BOTH OF THEM IF YOU HAVE TO I WANT HIM HERE IN THE MORNING I PAY ENOUGH I EXPECT YOU TO DO WHAT I WANT" and so on.
So the next morning the wife and I are on a plane with overnight bags. Get to his villa about lunchtime, shoutyman isn't at home. Oh, the client is there all right, but he's being his usual polite self. He invites us to lunch, served by his staff on a terrace overlooking the lake. After a small digestif he takes me to look at the pc that isn't working. It is sitting there neatly, with the power cable obviously unplugged. With a massive wink he says "oh, how silly of me, it must have been unplugged after all", and then tells me to fix it and check it all works. While I do, he starts on a conference call. Three minutes later I'm done checking, he puts the call on hold for a second to say he wants me to wait around til he's done, so I can demonstrate it's all fixed. Tells his butler to takes us to the garden to wait, and being us drinks, newspapers, etc.
Two or three hours later he finally finishes his call, it's five ish on Friday, and he says (with another wink) that the call took longer than expected and now he's done working for the week, so my demonstration will have to wait for Monday morning! We say we'll go check into a nearby hotel, he says nonsense, use one of the guesthouses in the garden, make yourselves at home, use the pool or the boats if you want, I'll see you again on Monday.
One full-service ultra-luxury romantic weekend by Lake Como later, I demonstrate to him that a computer that's now plugged in does indeed work. He thanks both of us for being so helpful over the last few months, and explains that he once tried to pay a bonus through our employer, but they insisted on taking a large cut, so he did this instead.
I put the problem down on the ticket as a 'power supply issue', which is technically about true.
