>A vending machine doesn't make notes of who buys its products. A vending machine doesn't keep logs of its transactions or of the payment methods used. Well technically the vending machine itself doesn't note this, but I've increasingly seen vending machines which accept credit cards. Thus your CC issuer knows where you were, when you were there, and can even make some inferences about what was bought based on the price. Personally, I keep an "entertainment" budget which I withdraw in cash, both for privacy reasons AND budget reasons. (Staring down into your wallet at cold hard cash makes you hesitate before buying that cup of coffee or other sundry)
