I don't sign my card as I feel that if it gets lost or stolen then the person who has the card also has my signature and would be able to copy it on receipts...
I now a lot do not sign their card but I don't understand what the big deal is.
No big deal, just lazy.
I never have until 3 weeks ago an electronics store in Poland called Saturn wouldn't swipe my card unless it was signed...
the only time i was asked to sign my CC was once at a walgreens in MI the lady at the counter was new to the job, didnt speak much english asked me to sign it then asked me to sign the reciept for $3 as well and then took both signatures and looked at them to make sure they match.
