Most cruiselines with the "auto tip" say that it is pooled and divided up between the wait staff & the cabin stewards...no mention of the behind the scenes people sharing.
The bar staff get someall(?) of the 15% they add to your drink order.
Maybe we should be asking each cruise line to spell it out more clearly.
I leave the auto tip in place and tip extra to those that make my cruise more enjoyable with better service
