I commute on Shuttle America a lot. They are some of the nicest pilots I have ever met. Keep it up.
Rode on a UAL 75 the other day and the CA must not have slept very well. He didn't seem too happy that morning, and barely said a word to me. Guess what? I still got to my destination.
Everybody lives a different life. Some people are mean, some people are nice, some people are dealing with issues at home, some people have ego's that barely fit in the cockpit, etc. No need to get all butthurt because they don't roll out the red carpet. Say "Please" and "Thank You" and you won't have any issues.
