I've posted a few times on here that I've noticed this and it can be frustrating. I flew to IBZ 5 times in CE last year, so you could say 10 flights in total and they weren't all the same level of service. A couple of flights were amazing, with menus, pre-dinner drinks service, hot towels and they got to the point I turned down more top-ups. Others so poor you received a single drink with the meal and I was getting up to see where the crew were and they were eating up front with the curtain closed and service seemed to be over after they'd served the food. To be fair, mostly on flights back from IBZ, so I guess the return flight was the only chance they got to eat.

Just wanted to finish with something positive though: when the crew get it right, they set a high standard. Far better than domestic flights in the US, even in (domestic) First, for me. CE leaves those standing. I flew MIA to JFK, which is around 3 hours, in F, got a small salad as my meal and a single drink. The single crew member then just walked off to help economy and didn't return for ages, leaving us with the trays for nearly an hour and no top-up, nothing.

Also, on the same flight, economy passengers constantly came through to the F toilet, often forming a queue. I asked the AA F lady why this is the case as BA doesn't allow this in CE and she said that they never stop them in AA! Got very frustrating trying to eat with people standing in the aisle waiting for the toilet.
