They are basically just store windows.
You do your shopping from the outside and tell the shopkeeper inside what you want.
And to make things easier for children or smaller Bhutanese, there is usually a little stepladder in front of the shop window
You’ll often also see people sitting on the top step of these ladders, chatting with the shopkeeper inside the store
That’s why they are usually totally overloaded with merchandise: strings of candy, bananas, shoelaces, mints, belts, pineapples, potato chips.
Sometimes these little shop windows display more stuff than the SEARS catalogue.
