Mauritius - LGW
Mine was MRU-LGW in J 12 hour daytime flight left 0800 arrived 4PM ish.
Served a not even full breakfast immediately after take off. Person next to me declined breakfast and crew said "Are you sure there's nothing else for many hours". We were served a light meal just before landing and there was nothing in what they used to call the club kitchen. Crew came out with water in plastic cups but other than that nothing pro actively offered for 9 hours of daylight flight
I joined many others in politely complaining to the cabin manager that we would like some lunch. She responded by bringing out the leftover cerials from breakfast and that was our 1PM lunch
Given the outdated IFE and not wanting to sleep because we had just got up it was a miserable flight. I commented to customer services and the response was that's what we offer on this flight
