I have a younger relative who works jolly hard – sharing the responsibility of running a very busy office that deals with many many folk by phone and computer.  In their line, some folk are so intense that they forget the company needs a holiday too.  So when some young entrepreneurs are battling away at the most trivial and tedious task, the professional cleaner can get it and the rest of the downstairs spaces absolutely clean and spotless.  In half the time.  Sometimes it’s not worth undertaking jobs just to save the modest fee once a week.    Best value is to make sure the cleaner can get around to every part of every room.  I recall an occasion when she couldn’t finish my niece’s because the dogs woldn’t settle down.  She left a note to suggest locking the pooches in a separate room further away from the seat of action!
