My maternal grandparents lived in the house next door to wharf, where my grandfather was the foreman (our town is on a tidal river which used to have considerable barge and coaster traffic). Every morning at 10 o'clock he used to come in for his coffee-break - always 'Camp' coffee (which was no such thing - it was made from chicory!). His break was only fifteen minutes, so he always poured the 'coffee' from his cup into the saucer and proceeded to blow on it so that it cooled quicker. He would sit me on his knee and let me have an occasional sip - I loved it. Can't abide it now though!
