When I go shopping, I am always very happy to present extra photo identification when I buy something with my credit card.
I know some people get offended if sales people ask to see photo identification, but the fact is it is a much safer practice, so people should welcome this request. After all, if a thief gets a hold of your credit card and learns to forge your signature you can be liable for some purchases, and you have to go through the hassles related to identity theft.
In this day and age, shoppers should expect to be asked for extra identification. I commend stores that insist on it because they are really looking out for their customer’s best interests.
