I am really pleased that you are talking to them. It is regrettable if TfL officers were not approached, but TfL is so new that people may not have known who to go to.
Let me get back to the question about how businesses might suffer if the system went two-way. That is plainly idiotic. If customers are trapped on one side of the street and cannot cross to the other side, they will do half the business. If people can start crossing the road, they can go both sides and business will improve
