Sorry, but the OP's comment on the FA's actions were valid, regardless of the meal service comment. AA's service in the last 18-24 months continues to decline, become more casual and less professional and shows lack of leadership and consistency from AA management.
I was on a flight this week in FC with meal service and the flight attendant literally did not speak, did not make any eye contact with the customers and missed about 25% of the service items. I fly AA almost every week and notice just an overall lack of professionalism and pride in the jobs of the FA's. I'm not looking for a CX experience, but just a simple, consistent execution of what they are supposed to be doing. It's really not that difficult.
