We originally booked a Chef's Table reservation for 4 people for our 15th wedding anniversary. After the initial booking we added a 5th person to our suite, so I called to get them added to our Chef's Table reservation as well, which was reflected in the app before and after boarding. When we arrived at Chef's Table with 5 people, we were led to a large table with only 4 seats left. When I asked about the missing seat the staff loudly stated the reservation was for 4 people and we must have made a mistake. When I showed them the app reflected 5 people, they loudly blamed us for "booking using the app", and said it was our fault for not calling. When I informed them we had called ahead of the cruise to confirm for 5 people, the staff realizing this mistake was completely their fault, doubled down and blamed it on us again without any explanation what we had done wrong. The entire situation was quite humiliating with the staff repeatedly blaming us in front of all the other guests and refusing to help us find somewhere else we could eat dinner.
We brought this incident to the attention of Francis, in the concierge lounge, who also refused to help us in finding somewhere else to eat. Despite multiple complaints, we never received an apology or explanation for the incident during the cruise or after.
