Your comments are valid, but your logic is faulty. I agree that service on ships generally has gotten worse over the years.
But please read carefully: I hae worked on 18 ships for 11 different cruise liines over the past 27 years. The internal tipping policies have been the same on every ship - ALL TIPS WERE POOLED. Please read that last sentence again. Its important.
When you gave me an envelope of some cash, it didn`t stay in my pocket very long. As soon as the last passengers disembarked the ship, all the service staff met at the Captain`s table in the diningroom. We all put ALL cash tips on the table for counting. Then the Maitre d` split and handed the money out to EVERYONE, based on a complicated point system administered by him. Today with auto-tipping, the smae system is in place. The only difference is that most of the cash comes from the Purser`s office. We still pool ALL the money in EXACTLY THE SAME WAY. NOTHING HAS REALLY CHANGED. Please read those last two sentences again. They are important.
To repeat, we ALWAYS knew we would receive a tip regardless of service levels. We still do know today that we weill receive a tip regardless of service levels.
Now please explain to everyone how auto-tipping has damaged service levels.
Once again, I agree that service levels have generally deteriorated over the years (I also observe that the quality of guests has deteriorated at the same pace), bu tyoumay be blaming the wrong reasons for the problems that exist.
