My business trip consisted of 4 flights and on my first one I happened to be on the same plane as my Stake President and his wife. They were literally in row one, and I was in the back row of this 34 seat prop plane - which was full except for the back row which I had to myself. It was like being on the school bus, except it was really cramped (5 foot ceilings and the like). Anyways I could see right up the aisle and saw the male steward engaged in a conversation with the said SP, and then pocket a card that was offered to him.
Way to go Idaho!
I on the other hand consider it a greater missionary service not to puke on my seat mates, or make the rest of the cabin endure the accompanying odor.
