They Know How Many Letters You Send

I stopped to get money at an ATM for my bank (Wells Fargo) this morning, and there were little flyers littering the area informing me that I can now purchase stamps there, just as easily as I can get money. There was no surcharge for the convienience. I instantly saw visions of new junkmail. "Since you are such an active user of the postal service, we'd like to offer you this wonderful automatic stamp licker for only..." And then I thought of that data building up somewhere, in a creaky database somewhere, and heard the dialog "Citizen IYTC804HI3 has purchased 845 stamps to date this year and isn't a registered home business owner. Red Flag." Maybe I'm getting cranky and paranoid in my old age.
