Normally I don't do shopping game unless I really do wanna shop. If you go to a mall, and walk out relatively empty handed, people notice, especially if you do it day in day out.
I remember seeing my mentor talk to an HB who was a Hired Gun at a shop. They were looking over G-Shock watches, and from a distance, I could tell he was sharp. It looked natural, near effortless, how he would switch vibes on the fly.
Later that day, he decided to actually buy the G-Shock, and by the time he was checking out, he jokingly added, "so does this watch come with concert tickets or something?" That's when the girl actually pulled out a set of tickets to the BMX show/concert. We were all blown away at the sudden gesture.
I believe the winner in this interaction was vibe; not exactly what he said, but how he said it. There's all kinds of vibes, like fun vibes, sexual vibes, even creepy and awkward vibes.
