fimo, Kiwi Flyer, you forget that some companies are cutting costs while still requiring staff to travel overnight and be fresh the following morning. Hence, it is not always up the the pax to chose the class of travel.
In all honesty, the OP has a very valid point - the flight attendants should kindly remind the pax about the non-recline during meal service and even offer to recline seat when meal service ends... Having said that, i must admit is a wishful thinking as it does not happen in reality.
