If you were to dispute a charge and had a card that wasn't signed, the merchant loses no matter what.
I had a customer get upset with me once because I didn't ask to see their Id since in the signature line it said see Id. I asked if SEE ID is their signature. They said NO. I then told them that if I went by the credit card companies rules that I would not be able to take their card since it was NOT signed properly. Just made them more pissed at me.
