The biggest factor I see is the absence of large supermarkets. There may be some out of town but within the Périphérique (ring road) boundary there are only small shops. Parisians live in small tenements, often six or seven stories high, without a lift; most don't own a car. It would be very difficult to go to Asda or Tesco, do a large shop, lug it up six flights of stairs and then find a place in your tiny galley kitchen to store the food. Parisians seem to enjoy the art of shopping. Why shop in one pace when you can still buy cheese from a fromagerie, preserved meat from a charcuterie and fish from a poissonnerie. Local loyalty and specialization still rule.
And then there is the French love of fresh bread. On any street at anytime of the day, you will see people carrying home their batons, often tearing the top off to eat on the way because they cant resist that delicious fresh baked warmth. We have three boulangeries in our area. They all display a mouthwatering palate of cakes and pastries and as if by some prior arrangement, they all take a different day's closing. Sundays are a particular favorite with the Parisian cake buyers. Gift wrapped cake boxes are carried home with care, as if the bearer were carrying a new born baby. We have succumbed to this tradition by treating ourselves to a modest tranche of Flan Nature, a cake so delicious it has become my guilty pleasure.
Groceries can be bought in little franchise supermarkets called Simply, Franprix and Monoprix - the equivalent of UK's Spar shops. The selection is usually varied and there are enough stores around to pick and choose. And as with the markets, the origin of the food is clearly marked and the majority is locally produced. In my first month in Paris I had an overwhelming desire for Scottish Oatcakes. I searched high and low and eventually emailed Nairns who gave me the addresses of three stockist in the centre of Paris but then last week I found the Franprix round the corner now stocks them - result!
On the whole the petit shopping experience is very enjoyable but as with everything there is a down side. Many (not all) of the small franchise shops appear to give no customer service training to their staff. The staff look and act miserable all the time, not just with étrangers like me, but with everyone. They appear to hate every minute of their job. In comparison to the cheery stall holders and family run bars I can't help wondering if their conditions of work are very poor and there is a resentment towards the predominantly middle class in the area. Unfortunately it is unlikely I will ever find out. It is a shame because like all the contributors to Le Petit Commerce these stores are providing what their customers want - minus the smile.
