There has been a thread on this from prior years. Re the sale of food soaring, the entire month is a celebratory period, marked by family meals and celebrations after sundown, as well as a light pre-dawn meal, so I don't see why this should be any surprise. Re fasting in general, and other religions have fast days, there should be no compromising pilot readiness and alertness because of religion--if a pilot is weak from whatever reason, and doesn't feel s/he is able to fly, s/he shouldn't be flying. .
