Stop, oh yes, wait a minute Mr Postman
Disappointed in his apparent objective of ringing the bell and dashing immediately away by the unmistakable sound of an elderly aristocrat limping slowly down a flight of stone stairs whilst jingling a set of keys (Lady Bracknell has, over the years, developed a particularly audible jingle for precisely this purpose), he chose to vent his irritation at the delay by folding her ladyship's Christmas cards in half so that he could squeeze them through her rather narrow letterbox.
Seconds later, Lady Bracknell opened the door and took delivery of three parcels. And subsequently bent down with some difficulty to pick her ruined Christmas cards up from the floor.
Lady Bracknell is sufficiently advanced in years to remember a time when those who worked in our service industries took a professional pride in providing an excellent service. Regrettably, those days appear to be long gone.
