My first camera back in the mid-70s was a Polaroid Super Shooter so I didn't have to wait, but when I got into 35mm, I would take my color film to a drugstore and wait almost a week for the pictures. I grew up in Northern Maine and I think most of the film was sent to the Portland area. In the 80s the service was faster, only a day or two wait.
There is a video on Youtube that is a few years old, but it is pretty funny. It's today's kids reacting to film cameras. What's funny is a reaction a girl has when told she would have to wait an hour for the photos (4:21). I wonder what she would think on having to wait for days!
