I've never shopped off-line in an Amazon store, so I can't tell you. But, in regards to online shopping, on Amazon, I do exclude every single purchase from their recommendation engine and I have recently began to hide the recommendation block with a CSS-based ad blocker, just in case I miss one. I just value my privacy. I don't even tell them my name at Burger King because I don't believe that they need to know my name when I go through the drive-thru. About 10 years ago, I decided that my default answer is always "No". "No, you do not need my phone number." "No, you do not need my zip code." "No, you do not need my name." "No, you do not need my email address." "No, you do not need my mailing address." Unless we're on a blind date, I don't need to give this info to someone I just met. It makes you very sensitive, then, to the frequency of events in which someone wants you to give up your privacy.
