In more than 5 years there, most on reserve, flying with captains from every base I never met anybody who had an issue. It's always "I head about this from somebody who heard about it from somebody". Best part, it was always junior FOs and FAs.

As for the one in the facebook comment, I wouldn't put my family on the plane if he were serving cokes and I'm not alone in that assessment.

Grow up. If you have an issue with someone, have the stones to air it in person rather than digging up old rumors in an anonymous forum.
