I know some feel that way Ngaire

...I very rarely eat desserts so I'm subsidizing those that do, to me this is a ridiculous analogy. With all inclusive, desserts are there for me to eat should I choose, sambuca (or other liquor) is there for them to drink should they choose.

I didn't feel that strongly one way or another about this until I experienced how much it added to the socialization and interaction with fellow passengers when you never worry about who pays for the next round. I would so much rather pay a bit more up front and be done with it!
