FWIW you do know that on QM2 in August/September at least during the Eastbound T/A, Fijords trip that the onboard Covid testers - 4 of them - hung out in the club and with the passengers. Though the testers are classed as both passenger and crew like onboard guest entertainers so they have above deck cabins. Conducting themselves like that is bad form no? If they go positive what happens to the testing operation?
