Scene: Person on Portobello Prom, standing outside The Beach House, looking at the menu. Me, cycling North-West up the prom.
I cycled towards the ample gap, and then noticed a dog appearing from behind the canvas barrier thing by the tables on the right (sea-side) of the prom. I watched, expecting the dog to probably cross my path to the people on the left, and then I noticed the almost invisible extending dog lead running the whole width of the prom, between who turned out to the owner on the left (With the end of the lead in front of them, not visible), and the dog that had just appeared.
Emergency stop, I stopped with my front wheel touching the lead. I said "You need to keep him on a shorter lead", the owner said nothing.
Dog was unfazed, and wandered back over to the owner, I cycled on.
