Mobile Post Office branch open for business in Clarbeston Road. In August 2015, the small Pembrokeshire village of Clarbeston Road has no permanent post office. For two hours each morning from Monday-Friday, this mobile unit is open for business in the layby outside Bethany Free Church. I was pleasantly surprised at the range of items available inside, such as an envelope for depositing cheques for a Lloyds Bank account, and a selection of greetings cards.
