It depends on the load. If you are the only person in F, then, yes, they will have one of everything. If there are only two then I believe they will have 2 of everything. Above that it it's going to depend a little on what others take.

Above all, don't appear demanding - if you ping the call buton five times before they have even shut the door then you aren't going to make any friends. But if you smile, ask politely, and avoid asking for things that could wait when the crew is at times of "peak load" then you can have (almost) anything you desire.
