I'd look up your local laws and see if it's legal. If illegal then you can be the good guy that saves him a ticket.
Are pedestrians limited by one way rules as well? I have never encountered such a thing, but I don't have a ton of worldwide sidewalk experience.
Your claim insinuates that it is legal to bike ONE WAY on certain sidewalks as well. Which I doubt is a thing.
