I generally crush new potatoes with my fork so they soak up more butter or gravy anyway, so I guess it's nice if the chef does it for me, except that a crushed potato loses its heat quicker, so maybe I'd prefer them to be left alone so that I can crush them as I go, although I suppose a chef crushed potato would have longer to soak up said juices so that would be nice, but then again I might want to put my potato into a specific area of plate juice for crushing to soak up my own desired mix of juicery... Oh I don't know, it sounds good anyway.
