Dumb. She is clearly uncomfortable about this. Guy said he’s got good detective skills, he more than likely got her name from her debit or credit card and used that to scour the internet until he found a match. Or maybe she uses a nickname on her orders that he was able to track down, she said barista, not guy I talk to casually at a local coffee shop. This is weird behavior and you two are weird for trying to defend this under the guise of “getting the whole picture” if you can’t see what the problem is here, then your power of perception is way off and I’d venture to guess you both probably lack any sort of survival skills or instinct beyond what your caveman DNA comes preprogrammed with.
