usually during break i will join my malay friends and eat in the
canteen..
then on first day of fasting, i feel that its a disrespect to
eat infront of them cause they are fasting, thus i join my chinese
friends in the canteen..
after that, i feel bad for leaving them alone 
Here's a tip.... ask them whether it's okay to eat in front of
them.
If they're okay with it, then it's fine. On my part, I'm
perfectly fine with people eating in front of me.
Just don't offer them your food and drink if you already
know that they're fasting. Now that would be real disrespect.
