I know there are definitely naive people out there that might give out their credit card info without thinking twice! Just today, I was in a fast food restaurant. I was quietly reading, there were only a few people in the seating area. All of a sudden, a woman's voice started reading off what was clearly a credit card number. I looked up, and saw a woman talking on her cell phone. She very clearly (and loudly) stated all 16 digits of the card, the expiration date, the CVV code on the back, and the name on the card (and even spelled the last name!). I wanted to go over and warn her that it wasn't a good idea to do this in a public place - she was lucky I was the only person nearby who heard her. But I figured she wouldn't appreciate my unsolicited advice! It's quite naive to think that there aren't already enough "bad guys" out there to deliberately try to get your information -- and here she was, basically giving it away for free!
