I think it's more a not-on-demand unless a pax specifically requests it policy. The rationale being that it is difficult enough for them to do a regular meal service on a 380 - so imagine the chaos serving 76 passengers individually. But if the odd pax requests to eat later, it may be up to discretion of the crew to try and fulfill this request.

For example, flying F, asked to be served the meal as late as possible. They were so good about it, at one point I thought they'd forgotten, but they literally served it so I could eat comfortably and when I was done it was time to buckle up.

Another example that I posted upthread, in J, asked to be served the dessert and cheese later, and crew were happy to do this on request. They can't do it for 42 pax, but it's not difficult if done for 3-4 pax.
