I've witnessed people in America using salt, sugar, and butter. Sometimes all three. Personally I just do a dusting of nutritional yeast, it gives it a cheesy flavor.
Watch out for United. That was the seatback camera airline. Qantas was the better of the ones I have been on. At least I could put the iPad with a camera in the seat pocket on Qantas.
I don't want food or WiFi. I want legroom so I can sleep. I don't want seatback entertainment. I don't want a complimentary tea towel, blanket, and neck pillow. I don't want your stupid cheapo earbuds. I don't want Tim Tams and that little sachet of Vegemite with my toast. I don't want your gross instant coffee. I don't even want a flat white. I don't care that you have soymilk. And thay muffin you gave me has egg in it. I told you I can't have egg. I don't want your little tiny tube of toothpaste with that miniature toothbrush. I don't want to watch Adam Sandler's Wedding Singer on that screen you have on the wall in front of the aisle. I want legroom. I want to watch the insides of my eyelids. I hate having to lay my legs sideways for hours and being unable to relax or sleep because I am knees-pressed against the seat in front of me. And that camera on the seat back freaks me out. Why why why. Just let me sleep.
Loving your family and wishing to hug your children? No outerspace mission for you!
