> When I get asked for my phone number, zip code, email address's etc... At checkout in stores, I give a polite "no thank you". Which usually results in a huff and/or an eye roll from the cashier, as if I'm expected to give this info for the privilege of shopping there. For the most part I don't even get the huff and eye roll anymore, they just hit cancel, input the store's postal code or something else and move on. Though I once had a cashier insist I give her my postal code after giving the polite no, she gave me some "I need it... for the system" or something. When I started giving an obviously fake one, I got the huff and eye roll. I wonder how many people would have caved. Hopefully just a new cashier who didn't know the appropriate thing to do in the case that I didn't want to provide details.
