The one and only time someone successfully picked me up in a store was Mr Big Lots. As I recall, when we first crossed paths, he may have smiled or made some innocuous friendly comment. Later in my shopping he turned up in my aisle again, looking like a sheepish ten year old boy, and asked me if I was by any chance a “single lady”. It was sweet and not creepy so I said yes.
The only cautionary part of the tale though - although he was terribly handsome, we probably were the least good fit of any of my dates. If I had met him through OLD he might not have made it through my screens, as I would have recognized how little we had in common.
