A franchise model would be cool af! Physical shops for bitcoin would need to be in the right locations to start with, in places where a lot of folk are already clustered. There's a lot of practical bitcoin related products you could be retailing as well - these miner-heater rigs, turnkey nodes, books, hardware wallets, GrapheneOS phones, not just various flavours of promotional material. And you could host training sessions and talks, book launches...Coffee and beer probably wouldn't go astray but might be harder to set up in some places, and people come and sit and read books about Bitcoin as well.

I'm sure once you identify a viable location you'll get one happening, but to make it into an online/offline thing, where other locations can open up and share access to a wholesale market it would help it grow a lot faster.
