No one is required to tip more in specialty restaurants. It's never been confirmed how much of the 18% tip in specialty goes to the server vs chef, headwaiter, girl at the door etc. We find if we repeat waiters in specialty the service is way over the top. So we always add to tip.
Plus auto grats, right? We normally take $1000 in 1s, 5s, 10s and 20s. We spread it liberally amongst the crew with no regard to quality of services rendered. Normally, of course
It has been reported widely here that no one is asked why ever! They probably assume as would make sense that those removing auto grats are tipping cash. In most cases this leads to tipping more than those with only auto.
Part of the problem is that Royal does not require any type of doctor form or proof of actual need of a accessible cabin. There is a form but its never really insisted upon on according to Royal staff. Unfortunately people search and book these larger cabins quickly upon availability with no accessible need. It's a shame but it happens.
