The most warped example of this for FTers would probably be the case of those of us (Yes, I was one of the idiots) who used Citi Thank You Points to get an airline ticket (paid for by Citi with their credit card), had to cancel the ticket for one reason or another and had to deal with the fact that the refund balance for the ticket went not back to the flyer but directly back to the credit card that Citi used to pay for the ticket in the first place. Result: no ticket, no refund money and all those Thank You points wasted. Definitely my all-time biggest travel (travail?) downer.
