Chat to other wall flies/bar tender. Dance around in your own(I’ve seen guys/gals at the salsa bars jiggling round and swinging those hips, there aren’t always enough partners). Smile, have a good time. You don’t need others to make it a good time, put out a relaxed positive vibe and it’ll come back to you
What about subscription services, food delivery boxes, Spotify, Netflix, anything you can pay for on their behalf to enhance their lives? Can always start out saying you got a two for one deal for 6 months so they don’t refuse outright and you can just keep on doing it.
