>Those receipts had your name, date, etc. on them
How, when I buy stuff in real world and pay with cash I don't ask for an Id Card, so why do you think the store needs names on the receipts? Is this something that happens in your country? For buying cars,land you need an Id, if I buy even an expensive electronics no Id is needed I just return the product and the receipt that has no name on it back.
I remember when my grandfather was doing accounting for a bar before Internet days, they papers were about the stuff not about people, like how many bear was bought, how much was sold stuff like that.
