Not your favorite O line.
When that other line fed me an egg salad sandwich with shrimp in it at tea time (I had asked the waiter what kind of sandwich it was and was told it was egg salad), I went up to the maitre'd to voice my concern that the waiters needed to be better trained as it could be life threatening to someone with a true allergy. (I have a shellfish sensitivity. Thankfully my only reaction would have been stomach cramps).
The maitre'd was very blasé about my concern and his only comment was that he'd look into it. So I then went to the head concierge to voice my concerns. (About that and our unclean room when we first boarded).
He listened to our concerns and I was told someone would get back to me. They never did.
So when we got home, my SO wrote O to voice his concerns. That was 3 years ago. Never heard a word. Trust me when I say that if we have a concern, Crystal is all over it.
