I don't know whether you are aware about the ground reality or not.
Medical shop owners are getting effect by online selling of medicine and many other business owner.
People, in general, are most sceptical when it come to buying medicines online.
Besides, medical shop owners are not bechara guys, they earn big margins if you compare the prices online vs offline.
I don't live in a big metropolis nor in a village but I am well aware of the ground situation.
Many med shop owners have started modestly, but they have grown their business in such way that their shops are now air conditioned. I know a med shop owner, personally, who has now a franchise shop of a well known bakery brand in Eastern India ( Mio amore, Google it ,if you are not aware), has a homeopathic shop and has good rental income too.
If one doesn't have business acumen and integrity, he / she cannot even can't keep a well made business from the previous generation.
