Is it even pantentable? (Score 1)

I just can't figure out how this sort of thing is even patentable. It's one bit of data about a customer's preference for type of grocery bag. Is this a business practice? It is defiantly not novel or non-obvious. So if i wanted to store information on if a customer wanted to be called by their first name or by sir or madam, would that be patentable (assuming of course that you didn't count my just describing my invention in the last sentence)?
