I would say that, anecdotally for myself, I get a "bad reaction" more often than "no reaction" when I refuse to give up PII to a cashier, and again speaking only for myself I am always polite about it (because I know they're just following the company policies). This may be because I know that at least some companies incentivize employees to capture this information, so when you refuse to give it up, they are in fact losing out on some kind of compensation or bonus..
