Cruise secrets: Crew member reveals what passengers should never do for this foul reason

Kinser explained that passengers should not shake hands with or hug staff on board.

“I feel passengers should avoid shaking hands or hugging crew members on a cruise ship,” he told Express.co.uk

“They may not realise how much sickness spreads through the crew on cruise ships, and many employees don’t keep up with proper hygiene.

“This is partly due to the fact that many crew members are working such long hours out on the ships and also due to cultural differences in what is considered good and proper hygiene.”

Kinser revealed that crew have a specific way of greeting one another on board.

“On cruise ships, crew members do not shake hands. They fist bump,” he said.
