After what he describes as an abrasive yet; ultimately; innocuous exchange with a flight attendant regarding a misunderstanding about storage on a long range flight; a B777-200 First Officer felt threatened by flight attendant comments about their control of his in flight meals. He; therefore chose not to eat a meal on the over thirteen hour flight.

Narrative

I was one of the First Officers on an international flight to ZZZ. The aircraft was a non-bunk airplane and has two first class seats for pilot rest and coach seats for flight attendant rest. After stowing my bags above the flight crew rest seats I proceeded to the cockpit and the Captain handed me the window shades for the cockpit and told me to find a place to store them as he did not have enough room in the closet in the cockpit. I went to the pilot designated storage areas above the flight crew rest seats and did not find any room to store the shades. I then attempted to return to the cockpit and found the galley Flight Attendant trying to store her bags in the closet aft of the cockpit. I was waiting for her to finish so I could return to the cockpit and put the window shades under the second observers seat. While waiting the galley Flight Attendant looked up and said; 'those won't fit in my closet'; referring to the shades. I said; 'I don't want to put them in there'. Still waiting she said; 'You didn't hear me; those won't fit in my closet!' I said; 'Again; I don't want to put them in YOUR closet.' She finally was finished and I secured the shades in the cockpit. The other relief pilot asked what happened because the galley Flight Attendant said; 'I hope he doesn't plan on eating tonight.' This is a 13+ hour flight and I wanted to try and address the issue with the galley Flight Attendant. As I went to the galley to speak with her another Flight Attendant said; 'You better not push her buttons; she controls your food!' Having been told twice by both Flight Attendants working in First Class I realized they were serious about tampering with my food. This is why I chose to not eat during this 13+ hour flight.
