Sorry it wasn't done deliberately because i couldn't think of an answer or anything. I get what you say but soon they will have to go to 1 Metre + like everywhere else and then there will be. In addition to that I'd like to see how many people actually use Castle St on an average day (Not the fisrt dat in glorious sunshine) before I'd estimate whether it would be too busy to allow pedestrians to socially distance. But Queen St would be doable as would the Hayes with no problem, and there are far more Cafe's and Restaurants round the Hayes than in Castle St.
