I noticed this too, but only after we took our last cruise on Carnival. The tip money was taken out the first day I believe. I was very unhappy after a "drink girl" didn't show up for 30 minutes into a show and my husband had to get up and walk to another waiter to ask for a drink. Our "drink girl" saw what he did, came over to him with hands on hips and snapped "YOU ARE NOT IN HIS SECTION! IF YOU NEED A DRINK I AM TO GET IT!" Then she stormed off. I couldn't believe someone who did not give us any service had the nerve to confront us for getting up and asking someone else to help!?
