As so often happens, people underestimate how much it actually costs to run a business.
That's why lots of bookstores have added cafés, non-book items and do author signings.
It doesn't seem to have changed the fundamental dynamic of the shift to online sales.
Some years ago, I went to a bookstore in my home town and discovered that a part of it was actually a bakery/café! I must admit I rather liked the idea.
