A good strategy for avoiding the (very) pushy traders is to "escape" through back doors. I found these children flying a kite made from plastic shopping bags via the back door of a restaurant in Kintamani.
As you can see, I had already made a purchase - this beautiful chess set was bought from traders who shoved it through the restaurant window
in order to make sure that I was honour bound to pay for it. I still treasure it to this day.
