Went food shopping with DD today (10 yrs old) who is autistic and almost completely nonverbal. Went well, we got towards the end and DD was stood at the end of an aisle, it's those aisles that have shelves there so she was stood in an open space with the trolley behind her, and I popped just a couple of steps away (not around any corners at all) to put something back and as I turned to head back to DD a security guard stood a few feet away says "yes, we have cameras, so don't even think about stealing that".
DD has a tendency to stare towards the ceiling like she's daydreaming, like a dazed stare, and she had her teddy in her hands, and that's why the security guard thought she was looking towards the ceiling for cameras to steal her own teddy
I politely sold the her that it was DDs and got the trolley and we walked away.
I get she was just doing her job, it was close to the toy's aisle so maybe they've had incidents of children thieving but AIBU to think it was also a little cheeky? DD obviously not affected by it, so I don't know why I am!
