The key point here is that he should have understood. The idea that passengers should shut up and enjoy the ride is outdated, condescending, and frankly - egotistical on the part of pilots and management.
Not sure if you have ever been to this part of the world but trying to explain a take off profile to the passengers would take forever. Most don't speak good enough English to understand how to use the PTT button on the headset let alone explaining why we are going to be doing a Cat A take off.
By the time they are on the A/C most are too tired from either the 12 hour shift they just did or the 40 plus degrees outside to be too concerned. Even asking the dispatchers to explain would be difficult.
