Mine doesn't even match what CS said when he read a standard description of how a line entry would appear for gratuity.
He said when gratuities are prepaid, the line entry would have language to indicate this.
I also have charges he didn't have an explanation for because he can't see the portfolio. For that I have to email guest relations.
We had a couples massage so the $199 appears for both of us and we did buy some merchandise which shows up on just mine but the smaller amounts show up for both of us and I've no idea for what. There is also a housekeeping charge which the CS thought might be if we decided to keep the laundry bag, which we didn't.
The positive and negative gratuity entries appear for everyone, multiple times with many repeated for a single day under each person. In comparison to hotel invoices (I don't remember our last cruise stateroom balance sheet since it was just before the pandemic) this thing is all over the place and looks confusing by design!
To answer your question, we didn't talk to anyone at concierge or guest services about reducing gratuities. The CS agent thought perhaps it was a negative value because we prepaid them but he didn't know why the negatives don't equal the positives which would have been expected had his explanation tracked.
