As an aside - and I'm still finding this unbelievable - community wardens ( red tabardy coats ) knocked on the doors of the terrace where my mother lives to tell her and her neighbours that they are not allowed to put their bags of household refuse on their windowsills for health and safety reasons Their reasoning was that the wind might blow them off the windowsill . They feel that the bags should be on the pavement . ( of course ,where dogs and foxes can rip them open and pedestrians fall over them .) I hardly like to add that what is really needed is for Southwark to come and collect the bags - on the day they said they would would be nice ,but failing that ,another day . But that seems a bit churlish ,it's early days for the new system and I'm sure the few hiccups will soon be sorted .
