Very amusing.
I have a friend at Chase (who will go unnamed for obvious reasons), who told me yesterday that Chase (including its Currency To Go personnel) was aware that people were taking advantages of certain mileage-related "loopholes," including purchases of travelers checks and cash back on the CO/Chase debit card, but that Chase was not concerned about these "loopholes," and had no plans to change any of its policies.
Looks like my friend was wrong.
