She was wrong to make a scene, Though I agree with her Flight Attendants should be respectful to passengers, I have always found Flight Attendants to be very respectful, apparently she came across an exception a bad apple, or maybe just someone who had a bad day, that Flight Attendant should at least get a warning to see if he has lots of complaints by other passengers of being disrespectful, rude etc, If it is a pattern and he has lots of similar complaints against him perhaps he should be fired it is bad for business to have Flight Attendants who are treating passengers like dirt, It is unfortunate She came across either a bad employee or an employee who was having a bad day and took it out on her. Still she should also be more Civil, Make a complaint, she is a Celebrity in the Track World and should have a better image, acting out has to hurt her endorsements, but she should speak up when someone is treating her like dirt.
The Flight Attendant was out of line and in the wrong, still Richardson should not make a public scene.
