I'm so sad for the servers who are unfairly treated by Disney if they don't receive an "excellent" rating. This has gone on for years; some day when I get to be in charge of
DCL that will be one of the very first things I change. So wrong to treat your employees that way.
But, it is what it is, and I understand their need to let us know how important that rating is to their jobs. We always react gently, and let them know we understand and to not worry. I've read of one poster here who
threatened to reduce their rating or their tip if them mentioned "excellent" again. Now that's pretty rude.
These wonderful, hardworking folks have a system that puts them in an uncomfortable position. We need to understand, sympathize, and guess what...they will appreciate the kindness and you will get it back in spades during your cruise.
