Well, I do try to choose where I shop in part to reduce the amount of spying I'm subjected to, but yes, this is of course a risk.

However, where a store might be spying on me when I'm just doing my shopping, it's guaranteed they're spying on me if I'm using self-checkout.

Honestly, though, the privacy invasion is only part of why I don't do self-checkout. Another major part is that I don't want to risk the store thinking that I stole something from them.
