BCH Adoption strategy: Dispensaries

Today a couple of completely unrelated reddit posts popped up with a common thread: marijuana dispensaries targeted for theft due to their dependence on cash. One an armed robbery, another was a smash and grab after allegedly targeting the owners.

This seems like the perfect use case for Bitcoin Cash. A budding industry (pun intended) which has no support from the banking industry. Bitcoin cash can provide them another payment method which reduces their risk significantly without the burden of ridiculous fees. And the UX of bitcoin.com app is surprisingly good.

I support the intention and direction of Bitcoin Cash and would love to see it get more widely adopted, though I don't personally own any. Has their been a coordinated effort to support Bitcoin Cash more broadly at dispensaries? If so, what barriers stood in the way...?
