>Do you memorize all the time whether you grabbed two or three bags of chips or exactly how many cans of beer etc?

Honestly, yes. What I worry more about is how well the names of items on the receipt actually match up to the products. From the summer I worked as a grocery cashier, I can tell you that people often end up confused at items on the receipt that they actually bought.

Combine that with mistaken items on the receipt and some number of more trusting people will just assume it's just a weird labeling of something they did buy and move on.
