14 minutes between buses is hardly unreasonable or so inconvenient that you cannot get where you need to be. Factually, fewer buses on the routes make the journeys quicker. You will know that TFL has had fewer customer journeys since lockdowns and - while picking up - they are subject to a Government funding deal. I think it is reasonable for the agreement to be reduced costs from (including) fewer buses - even is that is ONLY four an hour.
