"Some of the experience from Ireland and Canada has been that customers do not immediately know whether a shop sells cigarettes or not. Before this happens, shouldn't we consider adopting a universal exterior sign, like the 'tabac' signs in France, so that customers can immediately see which shops do and don't sell tobacco products?"
France does something similar with its pharmacies. You can spot the green cross from several paces which, for those in distress (which I assume smokers must be at times), is pretty helpful as well as being good marketing.
Anybody else got any ideas?
