That loyalty card tracks exactly how much beer you're slamming down. Think that data isn't being used? LMFAO. Do you think car insurance companies might like to know how many drinks you pound down every week?
While they may keep track of how much and what kind of beer you are guzzling, it isn't to give to your insurance company. It's to send you coupon and offers so you slam even more down for the same cost. I would worry more about the US Government and their internet and phone records they are saving than Safeway sharing information about how much beer you are "slamming down".
