If they ever swipe your license on their mag scanner, it contains everything about you.
Your state DMV sells your info to corporations for pennies, in fact sometimes under law it's required to.
If you ever need to return something they are entitled to your ID which has your entire address anyway.
Or here's another scenario, which actually happened to me:
I bought office supplies and one of the items bought was accidentally scanned twice.
I noticed this after paying, but immediately complained.
In order to refund my money for her mistake she insisted I provide my name and address.
I lied. I very obviously wrote a non existing person at a non existing address on the form she insisted I fill.
Do you think I was unjustified to lie in such a situation?

This is how car parking companies get your home address from your number plate to write you threatening letters.
The agency sold the details at a rate of around 50,000 a week, totalling 2.4 million in a year, to approved companies that give out parking fines and clamp cars.
If they just sell such information to any shyster that asks (and pays) for it there probably would be quite an uproar and it would almost certainly be counter to the EU data protection directive.
It really doesn't mean anything.
In the US (may be state law and not federal) it is a felony to give a false name/address for returns.
The reason why is people steal stuff or buy it cheaper in one store and then go to another to return it for cash.
However most stores do not require name/address if you have the original receipt. Only for no receipt.
