This is our local bike shop in Japan. There is a door in there somewhere. We managed to get about a metre inside but we couldn’t get the bikes in because it was even more messy inside. (click the picture for a bigger version)
This is how the shop has looked for the last ten years I’ve known it. I suspect some of the bikes were there all the time. It’s still open and selling and repairing bicycles so they must be doing something right. I suspect it’s to do with relationships in their community.
It may also be good service: they made a full checkup on two bikes and replaced two inner tubes and one tyre in a couple of hours. I guess this is normal when people use bikes for transport: it’s only places where most of the population use them for fun that we can get away with taking a day or three to make repairs.
