There are fun logic puzzles, such as the paradox "This statement is a lie", and of course more subtle variants of that theme.
But I have just come across a rather fun "complaint".
The complaint is that we accused someone of lying. Apparently, accusing someone of lying is a bad thing, and really bad "customer service". Obviously anything where the customer is not happy is, by definition, bad customer service. However, personally, I don't see a problem with accusing someone of lying, if, in fact, they have lied. I have a problem with lying.
But it struck me as an almost "clever" sort of complaint, as there is really no way to answer the complaint without it being true!
If I investigate and find that we did in fact accuse the person of lying, well, then it is true.
If I investigate and find that we did not accuse them of lying, as is the case here, then my finding is now accusing them of lying about the accusation of lying!
Either way, we end up accusing them of lying. Catch 22!
Oh well, I will have to agree that we accused them of lying or are now accusing them of lying. I'll not dispute in any way that we have or are accusing them of lying and not dispute in any way that it was bad customer service. After all, I would not want a "dispute" that might need "resolving".
I should say well done to the customer for coming up with a self confirming complaint though.
