The claim comes from a local newspaper, Nord Littoral, which said the chaos that affected 6,000 travellers allowed staff to carry off items like TV sets, paint and sport equipment from the 33,796-gt Rodin (built 2001) and the 33,940-gt Berlioz (built 2005).
“The port was blocked because of coffee capsules,” the newspaper said.
A ferry worker who is not a union member was cited as saying: “Basically they wanted to get the material for themselves - mainly the coffee machines.”
