AMEN. I was getting ready to type a long post explaining exactly that, but you've managed to shorten it to one sentence. If Disney thinks they can tack on an 18% surcharge and keep their business, they're sadly mistaken. I have 3 PS reservations for my January trip, and if they think I'll keep them with this JOKE of a rule they're wrong. I'm sure I'm not the only one.
A tip is a tip. It's very definition suggests it should be based SOLELY on the level of service provided. If your server paid no attention to you, left you alone for the entire meal, was rude, etc...they deserve nothing.........that's right.....nothing. They made no attempt to do their job, and for that they should be rewarded with a $0.00 where the tip is usually written. Too many servers think they DESERVE a tip as part of their regular wage, and they do..........if they earn it with good service.
