Oh and Cardiff market. I was going upstairs to a toy stall and I noticed something on the wall of the minstrel's galley. This old man came up and said, ''course you know what this was before?' I said 'no', knowing very well it had been purpose built as a market on the site of the open market. He said 'it was a prison mate'. So he showed me around all the old prison stalls and said look you can see where the bolts used to be, then his friend came and joined in it was really funny, I didn't have the heart to tell them
