From what I read on shipboard tipping it seems that my prophecy is coming true - that eventually the tipping charge will become a fixed charge and people will be expected to tip on top of that. Also tips are always in US dollars so that the $20 per day per couple becomes almost $25 Cdn. We have cruised when we had to pay $1.60 for one US dollar so the $20 per day became $32 Cdn. That made the cost of the cruise and tips very high. Americans are fortunate that they pay the stated charge and don't have to add on because of a weaker dollar.
