I want to thank HN for possibly saving my arse. During my lunch break, I put some gas in my car. During the fill-up, I noticed the anti-tamper stickers on the pump were all broken. I paid it no mind, finished the fueling, bought some lotto tix with cash, then left.

Came back to my desk, fired up HN, and read the article upon which we are commenting. Simmered in paranoia for a little while, then called up my bank and told them my card might have been compromised. New card with new number on the way.

Now just have to remind myself to check my transactions until the new card arrives.
