Its easy to set up a barber shop in India, actually all you need are the tools. Sometimes you see customers squatting on the floor, sometimes you see just the chair manifesting itself as a shop (I have a photo here "At the Barber") http://www.columbusmagazine.nl/azie_en_midden-oosten/india/rajasthan/reisreporter/fotos/203710.html
and sometimes a very simple shack. The barber here obviously liked the colour green, notice his razor.
