As a grocery checker, I also remember not typing the checksum. It isn't part of the product's ID, but manually typing in probably has a higher chance of error than scanning so what the heck?? Another fun fact: in the intro to The Simpsons, Maggie gets scanned by the clerk as a valid item with a price shown on the register.
