In the rag trade, and it's spring, chuck some flowers in the window, even if you're selling floral dresses... But what on earth are therapy culottes and therapy vests? Maybe they keep you Jung. The old ones are the best.
If you're chugging on the high street, selling charity (?), you're meant to get eye contact with your target while walking backwards. Great demonstration of eye avoidance tactics here by three pedestrians.
