>but does a restaurant or small accounting firm really need that?
Where I live in my part of Europe, most small restaurants, cafes, bakeries etc. only use a Facebook page and their Google maps entry to share their menu, phone number and interact with the customer base. They have no use to spend time and money owning and maintain a website, plus the advantage of even grandmas knowing how to update a Facebook page versus stuff like shopify or squarespace.
With a website that has a table reservation system you don't have to get interrupted by the phone all the fucking time by people when you're trying to chop onions or set tables.
