I can remember a time (1980's and earlier) when the modern version of the coffee shop didn't exist.
The nearest equivalent was a bar: Dimly lit, filled with smoke, loud annoying music, aggressive people, and a waiter coming around every 10 minutes to ask/demand if you want another drink. If you dared bring in some papers or a book to read, you'd get dirty looks, rude comments, or worse.
Thank god for the modern coffee shop and the shift in attitude.
