Tim has shared his grocery store experience. Now I must share mine.
I was waiting to pay for groceries at my local supermarket and decided to record the sounds being made by the price scanning device used by the cashier (that's not me in the picture, by the way. Tucking your shirt in to go shopping? Are you freaking kidding me?).
Well, the lane I was in was definitely beeping an A5, though you can hear a scanner in a nearby lane happily chirping a C6.
