Back in the 90s, gas station pump receipts still printed the full credit card number on them. Usually when you found one left behind, it was a corporate gas card that was useless.

But occasionally you'd find someone who left behind their Visa or Mastercard number.

Even in the early 2000s this was a thing in some places. I remember working at a store that printed the full CC# on the customer's receipt. As an employee, it would've been ridiculously easy to steal credit card information. You could just print a second copy of the receipt after the customer left.

This was especially workable in small towns, even back then you still need the zip code to pass validation, which small towns usually only have one of.
