Anyone know why....

95% of the Indian people who pass through my lines always have and buy gift cards to the store? Like they're even starting to buy giftcards WITH giftcards. WHY? Someone PLEASE tell me. And I want it to be respectful eg you are Indian or close enough to people who are that you know what you're talking about - not just speculation. Disrespectful comments will be deleted. (I'm not being racist, I just notice repetition. I couldn't give a flying fuck about who uses giftcards or not.)
