Sir: I find myself alternately puzzled and infuriated by the Royal Mail's unequal delivery times for first-class post. Letters sent to me from the Bristol area invariably arrive here the following day but it is a different story for letters sent from London and the Home Counties.
My latest record is five days for a letter posted in Slough and franked 14 January. It arrived on 19 January. Why should we pay 26 pence per letter for this gross inefficiency? I have known a second-class letter to arrive the next day.
