Confused about the expectation vs. reality in level of service- looking for insight

[IB2]

Personally I find people expecting the whole restaurant to celebrate their birthday as mildly annoying.  It happened twice on Britannia on my recent crossings.  Celebrate on your own table, by all means, but why should the staff have to make a lot of noise and effectively ask the whole restaurant to pause their conversations while a load of them are made to sing to a single guest?  It’s not as if having a regular birthday (until you get to 100) is a special achievement, after all - I think you’ll find that everyone has them….
