A cruise ship crewman was seen waving a giant false hand with the word 'bye' on it as two stranded passengers were left behind as it left the dock.
A video, shared online, shows Royal Caribbean ship Freedom of the Seas setting sail from St Maarten, in the Caribbean.
It shows two passengers who appear to have arrived late back to the liner, which was departing for St Kitts.
The person filming the clip says "they've missed it" before zooming in to a crew member, who can be seen holding a giant fake hand, with yellow nails and the word 'bye' scrawled across the top.
The crewman then waves the hand - but it is unclear whether this is at the passengers.
Sharing the clip on its Facebook page, Cruceros Puerto Rico commented: "Today, two passengers of the Freedom of the Seas arrived late to board the cruise and stayed on the island of St Maarten.
"They will have to take a flight to the next destination of the ship.
"It is important to be aware of boarding hours on your trips."
The Facebook page is dedicated to cruise ships which visit the San Juan, Puerto Rico port.
But Royal Caribbean insist the crewman was in fact waving to crew on another ship.
A spokeswoman told The Sun: "We regret the inconvenience our guests experienced due to the late return to the pier.
"Guests are encouraged to be back by all-aboard time.
"Departure times are routinely announced onboard, posted in shipboard newsletters and at gangways to keep our guests informed at all ports of call."
The spokeswoman later added that it is "a display of nautical camaraderie for the crews to wave to each other."
Mirror Online has approached Royal Caribbean for comment.
