I think the hustle won't be worth the squeeze, but you could offer - free - workshops in regards to LN and use a small pool of sats to have them play around with, and have them buy clothes (with sats sponsored by you) et cetera.

They learn something in the process and leave with a free gift of their choosing, making it a positive experience and maybe more probable that they're gonna use it again, although you'll have to heavily subsidize them with sats in the start, I think.

It could be useful, but it could also turn out that they simply go along with it as they get - semi - free stuff, then ditch ya - we're humans, after all.
