It's never really bothered me. I personally think the Britannia dining room is much nicer than the Grill dining rooms. Those dining rooms and their lounge are at the rear of deck 7 and I seldom think about them.
Just because you choose to spend that amount of money for a Grill cabin doesn't make you any better or famous than the masses. One evening I went up to the Grill dining room to see a maitre d' friend of mine and observed the diners coming and going and frankly I was much better dressed than some of them.
