When one has an unlimited credit card, well I appreciate it when they ask for an ID.
A couple of day's ago I made a purchase on a CC and the sales attendant had the perfect way to bring up ID verification.
She asked: "Would you like for me to verify identification on your card sir"?
I didn't hesitate for I knew I was the one toting my card! ; )
More can be achieved via honey than by vinegar...
And if it was stolen from you and the thief was at that store attempting to use it, and the reply was "no, thanks" then a thief could use it without verification?
A banker advised me to write "check ID" in the space for signature on credit and debit cards, so I did, and I thank clerks when they ask for ID to verify.
When it comes to my CC, I don't even sign them. I write in bold letters "VERIFY ID FOR SIGNATURE" on them. That forces them to check, and if they don't I immediately inform their management.
