I still remember my first cruise - I was first at the port so that I could be first in line to get into the NCL Vibe club. Not really quite sure of the process, I handed my bag and case of water (because that was still a thing back then) to the porter, and in an ominous, gravelly voice, he said, "And do you have a present for the bag man?" I interpreted his tone of voice to mean that something might, you know, "happen" to my bags if I did not give him 2$ a bag.
