NTA. For the technical legal reasons folks are mentioning, but also another broader one. The potential for profiling with this deeply troubling and wrong. I'm a middle class white mom with a doctoral degree and I'm guessing it kind of shows , so I likely don't fit whatever "profile" seems "suspicious" (not trying to rag on retail workers, it's just a reality of human bias). It's gotten to the point where I sometimes try to hand my receipt to these folks and they just smile and shake their head like "no, no, not you, obviously". I see other people get checked and...they often don't look like me. I feel like I could literally rob these places blind and no one would notice. If I were a young man with a darker skin tone I'm almost certain I wouldn't get that "you're good" smile like I do, literally every time.
