You have people varying from wanting all the information they can get, to others just wanting to know 'when am I landing, is there a time change, and do I need to put on my coat?'. After a long day in offices, they don't want a pilot yapping away with how many thousands of feet and metres, speeds in mph and kms/hr and how jolly cold it is outside. So the morning and evening businessmens specials tend to be a bit quieter on the PA. It's still easy to get it wrong, just like you got it wrong not using 'Questions' for a query like this!
