The title is bit misleading since the write up is more about bad customer service by Nepali shopkeepers. Nepali businessmen have mentality of "किने किन नत्र बाल मतलब" This kind of mentality is not very conducive to good business but they don't know any better because their ego is more important than business profit.

On the other hand, for marwadis, business profit is more important than ego, that's why they flourish in business.
