If a stranger at the grocery store started asking me questions about my luxury bag or next bag purchase I'd assume they're trying to determine whether I'm worth mugging in the parking lot.
When I was in Vegas that happened to me. I was in the bathroom in Caesar's Palace and someone said I love your handbag, let me see the inside. It was an LV and I clutched my bag and ran out. She/he (trans) was definitely about to snatch my bag and run.
