OK, as long as we're sharing war stories, here's another goodie.
In the mid 80's I was working for a small consulting firm that sold software and computers to go with it.
One of our computers was the Honeywell DPS-6. One thing about this is that had removable hard drives, which is a round phenolic platter that one can fairly easily remove and replace. That's what our clients (were supposed ) to use for daily backups.
Well, one morning I come in and I get a call d=from one lady, who is well known to be a ditz, frantically asking us to call.
So, I call her and she asks me if the manufacturer's service contract covers discs that were damaged by a head crash. I said that's not a problem.
Now, she asks me if it would cover more than one disc. Now, my spidey sense is tingling and I say, I'm sire it'll cover two since it takes that many to actually determine it's a hardware problem.
Now she asks if it would cover more than two. Now, I'm really nervous. I ask how many we're talking about.
She says "thirteen" Now, while banging my head on the desk, I ask how she could go through so many.
She says she thought they all went bad.
We covered three discs and she had to explain the other ten to her boss who got hit for the replacement costs.
