On my last cruise aboard the Carnival Pride, they left an envelope for gratuities to the Maitre' De. The Maitre' De that we had, we never saw because he stayed in the lower level of the Dining Room the whole cruise and we only heard his voice. I think the only time that I did see him was the last day at breakfast when the Dining Room was being inspected. But the assistant Maitre' De was very kind and went around to all the tables and said a few words. Is there a need to tip someone like the head Maitre' De in this situation? Thanks for your replys.
