I got a letter from my credit card company the other day ... it said:
Congratulations! We have increased your credit limit to $XX!
Apparently they thought increasing my spending limit was a good thing -- the CONGRATULATIONS! part was heavily emphasized (see below).
They didn't tell me that I could only spend the increase on DingDongs and that I had to curtial my spending at Old Navy. No, the letter simply said I could now spend more money.
