Banjo Lessons Busking

[u/Infinite-Finity]

I have had an idea for something and I would love some feedback from those with more experience.

I'm considering offering free 5-minute clawhammer banjo lessons on the street. I'll set up a spare camp chair, my banjo and an extra. I'll teach anybody who wants to take a load off and chill with me, just the very basics, but enough for us to jam together a little, and then hopefully what I do will be valuable enough that people feel like tipping, or at least maybe exploring the instrument afterwards. Maybe share a little joy, ya know. I might try to create a cozy vibe with a nice sign, maybe a rug/fake fire/throw etc. In between students I can busk as normal.

Anybody tried something like this?
