"Can I have your credit card number?" by sTeeTs

For some odd reason I had this happen twice today while answering the phones. Why is it that some people like to recite their credit card number in groups of three? As you can see, the illustration to your right clearly shows the numbers to be grouped in fours. This may seem menial, but it completely fucks me up. It's as if the numbers no longer make sense to me whatsoever. It's comparable to giving someone your phone number, but pausing after the fourth number. You just DON'T do it.
