Personally, I always take the attitude that sometimes things don't go right and it's important to go with the flow. Things don't always go to plan, and all of this is definitely a first world problem.

Self importance can be a considerable block to appreciating what we already have. I understand that the OP was disappointed, but it should be put into context. I'm sure the ride was comfortable, the 23" screen was still visible, and the OP did not die of starvation during the flight.

By all means complain through the appropriate channels if you wish, but remember you're already very privileged, and waiting 20 minutes for service in first class is a far cry from not being able to afford eating. Most of the world lives that way.
