"My supermarket has a savings scheme, in exchange for my personal information. The way it works is that the cashier asks: do you want to join this savings scheme? If the customer says yes, they give you a form to fill in your details. If you say no, they leave you alone, and you miss out on the discount or gifts." Hahahaha, yes, if you don't join their club, they don't collect personal information.
Or you just provide someone else’s information. Who says you have to share your true name with your supermarket? Unfortunately it’s very difficult to lie to google
Don't worry, depending on the state, they have plenty of other ways to personally identify you. No need.
