Some credit, please

Upon arriving home, I have discovered that it's somehow become so much easier to use someone else's credit card to pay for random shit. I feel like fool. At CVS, at Border's, you know, I just stand there waiting for the credit card slip, ready to dive for the pen to show that "oh yeah, this customer's with it" but actually no, they don't need me to do that anymore. Not that the old way really did that much for security in the end anyways... for years I signed with a signature that in no way resembled the one appearing on the back of my card, but seriously. Damn.
