Tallg non muslims have no retricion to eat in ramadhan in most muslim countries including Qatar. The only thing is that they can only give some repect by not eating so openly but they can certainly eat in offices. This happens here in my office as well, no body fells bad about that and no one bothers & cannot restrict any one.

By the way fasting is there in all abrahimic religions not just in Islam.

Want to mention another fact that you mentioned that you cannot think about the fact that people do it in the name of ALLAH almighty, well can you could have explain how come?.
