Ugh, I feel your pain after having my Visa toyed with last year... not fun to look at your statement and see charges for plane tickets!!!

Interestingly (and annoying but also relieving?) Visa is now super-vigilant about my card. We were out to dinner in June and the waitress, unbeknownst to me, double-swiped my Visa. Well, they froze it immediately and I had to call and confirm that I did indeed go to a movie and have dinner at Moxies!
