Curious Pax,
We don't always get a chance to talk to the crew...
A lot of the time I find that passengers don't believe what they're told anyways. Years ago, we diverted due to the airport we were going to (XXX) being fog bound. We sat at alternative airport for quite some time due to many aircraft diverting to the same airport. We told the passengers exactly what was going on, but plenty of them told us there was no fog at XXX (!). It does make me chuckle when passengers think we delay them just for the hell of it, as if we don't have anything better to do...
Plenty of times, I've had passengers ask me for the "real" reason for the delay when we've already announced the reason.
