Completely different from what @Rain Man was saying as to all the large eyed Bangladesh tourists that do lots of sight-seeing, get all excited and come back again and again to do more shopping (greater selection and less chance of import tax on the goods).
You are free to come to a conclusion based on posts of a troll in an internet forum.
The original article also paints a different picture. I mean why do so many Bangladeshis return and return whenever they can back to India to spend more and more? As another Bangladeshi poster said in another thread...even the horlicks you buy in Bangladesh is from India. No wonder.
There is nothing in the article about the economic class of the tourists and surely nothing about what you are saying. The Bangladeshi tourists visit India mainly for medical purposes, they don't really "return and return whenever they can back to India to spend more and more". How many Bangladeshis actually drink Horlicks? I doubt the number would be anything significant. GlaxoSmithKline has a factory in Bangladesh though.
