"Do you think it's strange that those patrol officers saw us arriving here, heavily laden, and obviously planning something, yet instead of coming over to question us, they quickly walked away?"
"You haven't been here for long, so you might not know about this, but it's actually an unwritten rule."
"When we appear on the deck with our large and small bags, others, including the patrol officers, will assume we are preparing to leave from here."
"Normally, even though the patrol officers won't obstruct us from leaving, they would, according to regulations, need to control us first, then inspect our luggage. Only after everything checks out with the rules, would they let us leave."
"However, going through such a troublesome process means that even if they find some special items, since it's all happening in front of everyone, the patrol officers would have to hand everything in."
