There are not that many Sikhs around. 22 million in a country of 1.2 billion. Most live in the north. You can't easily go get food from Sikhs.
Also, every week a Sikh group feeds the homeless and disenfranchised on East Hastings in Vancouver.
So yes, I can in fact easily get food from the Sikhs. :) And I have, when I was amongst the disenfranchised. It was very appreciated.

Google Maps...really? I don't mean offense for being obtuse, but I sense a bit of first-world bias in your assessment.
I would imagine that for someone who is so poor that finding a simple meal is a daily struggle, what I might perceive as an inconvenience is almost certainly a show-stopping barrier.
