Just my 2 cents from an old retired guy. When you are unfortunate enough to fly with a CA who is a jerk, try to take it as a learning lesson on how not to act when you move to the left seat. Also remember, not all the jerks are in the left seat, there are some who are in the right seat. The ones that are a jerk in the left seat were probably one in the right seat. They don't include a "how to be a jerk" video when you upgrade.
