Completely unrelated but, I asked it the popular "Where did the dollar go?" question and I'm pretty sure it gives the wrong answer. Maybe it is prone to some fallacies?

Prompt:

Three friends have a nice meal together, and the bill is $25
The three friends pay $10 each, which the waiter gives to the Cashier
The Cashier hands back $5 to the Waiter
But the Waiter can't split $5 three ways, so he gives the friends one dollar each and keeps 2 dollars as a tip.
They all paid $10 and got $1 back. $10-$1 = $9
There were three of them 3 X $9 = $27
If they paid $27 and the waiter kept $2: $27+$2=$29
Where did the other dollar go? $30 - $1 = $29

ChatGPT:

In this scenario, the other dollar likely went to the cashier as part of
their tip. In the situation you describe, the three friends paid $10
each for a total of $30. The cashier then gave $5 back to the waiter,
who gave each of the friends a dollar and kept $2 for himself as a tip.
This means that the friends paid a total of $27 for their meal, and the
waiter kept $2 as a tip, for a total of $29. The remaining dollar likely
went to the cashier as part of their tip. This is a common practice in
the hospitality industry, where the waiter and the cashier may split the
tips they receive from customers.
