ok, i have never heard of the stranger coming up to you and saying whatever… and i am not aware of bin laden making any such comment… but i can offer this:
Muslim dominated areas in the city of Bombay, India, had for a while stopped selling coke and pepsi and some other drinks considered “western” in restaurants and stalls. I had heard about this but not experienced it till i had gone out for dinner during a muslim festival to a predominantly muslim area. I was surprised that they did not serve any bottled soft drinks, except for Indian made ones, with dinner. I am not sure whether this is still the case. And i am not sure what their reason for boycotting coke and pepsi etc. was.
i did a search on some of the leading Indian news websites, and these are the matches i got:
"
The boycott of US and British products had come following a series of meetings by several Muslim groups, especially hoteliers, to protest the killings of civilians during the US bombing of Afghanistan. The IHA had joined the agitation and exhorted its member hotels to stop stocking and serving US products. The Darul Uloom at Deoband issued a fatwa banning US and Israeli products.
From October 28, the ban had become total with most Muslim localities and shops clearing the products off their shelves."

So, yes, there was a ban (or boycott, actually) on coke and pepsi and other US and UK based products in some areas of India for about a month or so in october of 2001. Some places might still not be serving these products, but it seems that most have withdrawn from the ban due to commercial reasons.
