NEVER do these 5 rude things on your cruise.

using your hands to grab food in the buffet and you know people that do this skip right by the handwashing station oblivious to the world it's gross so stop doing it

treating the crew poorly I've seen this happen too often including a lady who tried to get me to join her tie raade about a crew member's English

not understanding elevator etiquette don't rush onto the elevator and not let people off first that just creates a traffic jamp

hallway Runners and loud talkers especially late at night if people wanted to hang out and party they would have stayed at the bar until 2:00 a.m.
