Thanks for your input everyone! Airport sandwich it is.

(The only other time I flew FC, I had upgraded because I wanted to use the time to do some urgent work on my laptop, which there's no room to open in the cattle car seats. But I was annoyed that I had to wait for the FA to remove my food tray so I could use the seat tray for my laptop. However, I had fun imagining what the staid businessman sitting next to me thought about having to share his row with a chick with spiky green hair. )
