Eat the damn chicken and stfu?
You know how cabin attendants about half of the time have no idea what happened to the special menu you reserved/ordered when buying your ticket, made sure to mention again at check-in and such? It wasn't my problem this time, but on my last flight on Lufthansa the passenger sitting diagonally behind me had this on his hands:

Cabin attendant: 'Beef or chicken?'
Passenger: 'I ordered a vegetarian menu.'
Cabin attendant: *pretends that she cannot imagine it, addresses other cabin staff ostensibly*: 'Did we have any special menu orders? I didn't see any.'
Other Cabin Staff: *murmurs something and pretends to be somewhere else*
Cabin attendant: *raises and drops shoulders, addresses same person again* 'Beef or chicken?'
Passenger: 'What about what I ordered?'
Cabin attendant: 'You must have forgot. Beef or chicken?'
Passenger: '... I don't eat meat.'
Cabin attendant: 'But this is chicken. Chicken?' *tries to push the tray his way*
Passenger: 'I don't eat meat.'
Cabin attendant: 'This is chicken. See?'
Passenger: 'I don't eat meat.'
Cabin attendant: 'But it is chicken.'
Passenger: *wtfbbq11? expression*
Cabin attendant: 'You'll have the chicken?'
Passenger: *stubborn* 'I will not eat meat.'
Cabin attendant: 'Here you go, chicken, yes?'

This went on for another ten minutes; I wavered between snorting and getting up and telling the cabin attendant to stop acting stupid (in the seventeen years that I lived in Germany no one ever tried to convince me that chicken isn't meat), and she was giving other cabin attendants a bad name (one of my childhood friends became one too) but in the end I did neither, coward that I am. You don't want to antagonize people who serve you food. In the end the passenger lost and had crackers. The beef I had wasn't bad at all for airplane fare btw.
