Thank you all for your replies.
I owe you all a clarification: right where I work, they will lock all pantries and cafeterias during Ramadan. the only non-public descrete place I can eat in is actually the toilets!! and imagine a pregnant woman with morning sickness doing that, yukk!!

I am surrounded by muslim colleagues whom I respect and do not wish to alter their fasting in any way, and I DO think they will mind if they see me munching at my work station!
The atmosphere inhere is somewhat very conservative and I don't want to be misunderstood..
