You, Ma'am/Sir, seem like a textbook case of someone with a very 'Low Self Esteem'.
If someone is being rude to you because they are offering you help, you simply can't take the disrespect.
The jumpseat DOES not belong to the captain, it belongs to the airline. The airline management is the authority that made it possible for pilots to jumpseat. NOT the captain!
If someone is rude to you, you must do something about it! Not just take an insult, like you did, and feel you deserve it because it’s a ‘freebie’ you’re getting in return!
