The flight attendant on the flight was extremely unprofessional and obnoxious. He treated the entire plane as if we were on a seventh grade camping trip. He thought he was funny but was actually rude to us while we were on the ground waiting to continue to our final stop. It was like being stuck with a bad comedian for four solid hours. We flew from Chicago to Long Beach to Reno over 5 hours and they did not have any food other then graham crackers. Because of being delayed no one had time to get food in the airport between flights. Terrible experience and Southwest should look into this crew member.
