Forgive my naivete. I've only flown business class once. On that occasion, I got hot washcloths and a snack that was a little more frou-frou than a typical coach snack. Nothing else special, except private bathrooms, I think, just for us.
But when people talk about the service being great in first class, what do you mean exactly? When I'm on a flight, there's really almost nothing a flight attendant can do for me other than serve drinks or food now and then. So what additional service am I going to request or find worthwhile paying for? I can understand liking the greater amount of room available.
