When I lived in a different building there was a gas station across the road. It was closed on all holidays so we would sit out front and watch people all day long come and try to get gas. They would sit there for up to 10 minutes and realize no one was coming out. Then they would go to the door with this 2 foot wide closed sign and try the door then they would look in the window to see if someone was there. Then they would finally get it and go home.
