It's definitely NOT insulting. Any fasting muslim who feels insulted because a non muslim is eating beside him is losing the spirit of fasting itself! Ds is why Allah (SWT) says "only Him deirectly rewards a fasting muslim"..SIMPLY BCOZ wen that muslim has a full option (nt because he's in qatar) to eat and drink,that same muslim has chosen to refrain from such. Fasting in islam is an act of worship for all muslims NOT a culture for d qataris or saudis!
