Number 1

I was in Walmart today, and as I was checking out I used my debit card. It dawned on me, as I was punching in my pin, that the number 1 on the pad was the most worn out number. So I started thinking that I bet for the majority of people, somewhere in their pin is a 1. Most people have a one within their four number pin, and that's why it is so worn out!
Kind of random, but that's what came to my mind, and I thought it was a cool observation!
I bet you'll never look at the pin pad the same after reading this! haha
