I worked in the middle east many years ago and went through several Ramadans. As I recall during daylight hours everyone fasts (unless exempt) and at sunset families gather for a well deserved meal.
So I can understand that during daytime flights you need to show consideration for fasting passengers, but if it is a night time flight (where to all intents and purposes everything is normal) why should eating and drinking (in the lounge or on the plane) be any different from normal?
I'm flying BKK - DOH - AMS tomorrow evening and will report back. Unfortunately I'm on a P class fare so lounge info may be limited.
