i see the same attitude every year during the baisakhi mela when thousands of sikhs visit Lahore and throng the shah alam market. They buy stuff like crazy...all discounted heavily.. you have to take my word here coz you have to see it to believe it. i have friends with business in shah alam market and they all say that it has become kind of a norm there that sikh traders will not be fleeced or charged the real market price.
on the other hand i visited Mumbai 5 years ago... loved the city, the bazars, the pani puri near hill road, the books i bought from crosswords but for the people there... well all i can say is that i was refused a drive on auto the moment he knew i was from Pakistan, the person at crosswords stopped helping me the moment i told him i was from Pakistan, the fear that i experienced in dadar when i introduced myself as pakistani and i still remember the way i was treated during immigration at Mumbai airport. Bottom line india as a country was amazing but some of the indians were very hostile and unwelcoming. I believe this is because of the Indian media... during my 10 day stay there and discussion with colleagues it became apparent that they have been fed a wrong image of Pakistan, one that is not true and based upon a narrative of a sick minded person or an organization. The same is true for Pakistani media as well but indians do it at a level that is beyond our capacity and capability now.
my 2 cents
