As I have already said the Friday goat market is more of a social gathering for men and boys rather than a thriving market. The selling of goats may not be a roaring trade but the 'pop-up' barber is doing very well.
Just look at what he needs, a few sticks to hang his towels and mirrors, a couple of chairs created from scrap wood, A plastic comb and a pair of scissors and skilled hands. You can see that business is good by the abundance of hair under the chair of the little boy.
So simple - so Bangladesh.
