If you're going to go to the trouble of making a fake cafe or bookshop, you might as well make the real thing. The point of the fake bus stop is that it's trivially easy to do.
More importantly, the bus stop attracts seniors who are trying to leave the facility, which is dangerous because they aren't able to do so safely, and are likely to end up lost and dying of exposure or exhaustion.
A fake cafe or bookshop wouldn't really be any more useful than the cafeteria or day room that the facility probably already has.
Well, it could be useful to create a more comfortable atmosphere. This hypothetical assisted living center would be set up to look just like a small open air mall surrounded by apartments, except all the workers in all the shops are nurses.
Just to comment on myself: I may have misunderstood the meaning of the word "fake" in this context. A "fake cafe" could still serve coffee, just not to the public at large.
