The submarine's pipeline is connected to a pool, which, besides the entrance and exit via ladders, serves as a second entrance and exit.
Here, the submarine's staff checks the tickets of those boarding afterwards and issues wristbands; they also handle the collection of tickets and wristbands for those wishing to disembark, and see them off the ship.
A large number of fishmen emerged from the pool, and the ticket inspector routinely stepped forward to check tickets and handed out the wristbands to everyone present, instructing them to put them on.
A few fishmen, with helpless expressions, began to converse with the ticket inspector.
They told the ticket inspector that this was their first time on the submarine, and they weren't aware of the rules, never expecting that they would have to wear something resembling a shackle to board.
In their culture, shackles are considered to be extremely heavy items, and wearing shackles is tantamount to committing a heinous crime.
