ALLOW ME to update Mr Porter, who writes that in the 1980s I displayed my public-spirited side by erecting memorials to police officers killed on duty, whereas in the 1990s I took to complaining in restaurants (Diary, 30 May). My charity, the Police Memorial Trust, erected 10 memorials in the 1980s. We put up 12 more in the 1990s. As for complaining in restaurants, if Henry Porter sits through dreadful food and service - and filthy glasses as we were given at Cliveden - in silence, then he is doing no one a good turn. A bit of complaining, when deserved, smartens things up for everyone.
