Also doesn’t cost anything to bring some joy, or if not joy, at least novelty, into people’s lives.
I'm sure your intentions are good but you will be making a lot of people uncomfortable in your attempt to connect with them.
I think you dramatically overestimate how many people are made uncomfortable due to your own anxieties about it. I also think you’re missing out on little opportunities for joy in your life.

There's better places for that than public transit or a plane.
There are also plenty of worse ones.
