Certain Indian food is eaten with rice and some with bread. If you are using the wrong one that is the only reason you would get strange looks. If you use fork and knife then you would actually get strange looks.
I found that was true in India. Here, some people are weird.
You get looks when eating with flatbread? Really?
Hmm, I'm going to be much more self-conscious from here on out.
Nah, don't.
Here in the UK. You get looks if you go to an Indian restaurant and eat flatbread (Naan) with a knife and fork.
