I've travelled across the globa and seen it with my own eyes,.. that's how i know. Even in my college the only other pakistani (a lahori) scammed around 5000 swiss francs from a whole bunch of people. he gave other pakistanis a bad name.
After i left college i found out the next pakistani to join (another karachiite) was a full blown stoner,... great for the image of our country? I think not.
