The only female flight attendant on staff was extremely rude to my father who recently suffered a stroke and cannot walk, use his left arm, or speak english… she yelled at him and embarrassed in front of everyone multiple times…. We are frequent fliers of southwest and i feel very uncomfortable flying with a flight attendant who does not know how to treat clients and was unaware of his handicap needs, language barriers, and racist. All of which, is unacceptable. Shame on you southwest.
