MM I am with you , and not going to criticize you for your complaint . If today I post that my boss has not paid me because I have not done the assignment he has given to me and he is unfair, people will start telling me I am the one who is wrong (which in that case I will be), so its hostess job to clear your table, as it really is against the safety rules and even a bit of turbulence may cause any injury. Secondly it also cause discomfort while sleeping, as economy class seats are already have very less leg space.
You have done right to complaint against her. Though I wonder if they take any action or just let her go as she is overworked :-0
