The story behind this is that some time ago, the shop owners added the blue illuminated sign without first applying for or receiving the necessary planning permission. Subsequently application was made for retrospective planning permission which was refused. It appears they can keep the sign but not illuminate it. There has been local media coverage suggesting that it does not fit in with the local character of the town. Sorry to bring local politics in. I of course express no opinion or judgment here.
haven't they heard of 'progress'? although i must admit the façade of the store ruins the lines of the building. it could be a landmark though, like "turn left when you see the blue market building, etc." 😊
