I do notice small businesses using Facebook in lieu of a website - I find myself having to check Facebook to find today's specials menu at the two cafes I normally buy lunch from...
Not sure who is on the wrong side of this garden's wall...
Many small businesses also seem to depend on FB for communication.
I can avoid the latter, but my consulate is why I can’t delete my FB account.
I don't demand anything of a business, but if they direct me to a Facebook page, I see nothing wrong with letting them know that's not something I can use.
