Thanks aquarius moon and sunbob. Great to hear of another store boss doing the sensible thing and closing the door when it's cold - also opening it when it gets warmer outside when natural ventilation is the best thing. Quite right about pubs/restaurants, and we do cover them, though on the whole these tend to be better than chain stores on door policy. It is simply not true that a closed door deters custom - so many shops of all sorts now trade successfully behind a closed door in winter that it would suggest something seriously wrong with a shop if people don't bother to open the door to get to what is on offer (which is unlikely and we haven't seen that yet). There are also reports of customers staying longer in an even, comfortable temperature when the door is closed, and spending more. Shoplifting also goes down, saving more money. A no-brainer. Note taken of the comment on the Forest Hill Co op.
