Hey, it's free, (or at least it's "included" in the cost of the cruise), I don't care what brand it is.
At home I buy what ever is cheapest...and that rarely is Coke or Pepsi.
I had to "negotiate" a new soda contract three years in a row for my son's Little League. RC won the deal the first year, they "donated" $500 for us to switch. Pepsi won the next, they "donated" $500 and a scoreboard. Coke won the next year, "donated" $500 and 2 scoreboards. Funny, we get parent complaints everytime we switch....but the KIDS don't even notice.
