Have to agree with the advice you have been given already. Live and learn, although sometimes it's not what we want to hear. You are a passenger for a week. As soon as you leave, someone else is occupying your cabin, your dinner table, etc. and another face has taken your place.
I don't mean to sound too harsh but remember, these crew have a job to do and they deal with different people weekly, week in and week out.
Enjoy the memory of your cruise and learn from the experience.
Happy future sailing!
