This is almost two years old, but I suspect it's still relevant.
I've even run across instances where credit cards get used in some possibly unexpected ways. For example, according to creditcardsmagazine.com, it seems that police in Boca Raton, Fla., have found that "nearly 700 people used credit cards between April 2000 and March 2005 at Dreamescape, a brothel.. While some clients paid in cash, one 80-year-old man charged more than $36,000 on his credit card in the 232 times he visited the establishment, according to police." Yikes.
