"And it is only getting worse, with more and more normal retail companies seemingly now wanting my data when I buy something over the counter."
Yep. "Would you please visit our website (store.giantadfirm.com) and fill out our survey" and they'll happily give you a small glass of sugar water with your next purchase for giving them a load of your private information that's tagged to the code on the receipt that pinpoints the date, time and store you patronized.
The staff never seem to get my statement that they aren't paying enough for my information (I'd lie anyway).
