"If you're a hair salon, or a tattoo artist, or a restaurant, or whatever, please just have a fucking website where I can go and see your rates and hours."
It's true there are some businesses that only publish rates and hours on Facebook
But it's probably relatively small number
Given the choice between (a) a business that has a listing accessible via yellowpages.com, Google Maps, etc. and (b) one that has a social media account but no listing in any business directory, it stands to reason that there will be more opportunities to choose (a) than (b)
There are also other reasons to prefer (a) to (b) besides avoiding Facebook of course
