Very sorry,the protocols to identify crew was not evident on Aurora R407,crew working although obviously unwell in dining rooms One instant, waiter one evening wearing blue mask,when asked why he said that he had the cruise cough. Next morning no mask, dinner time no mask evening no mask never wore it again, his number two quietly coughing for days. Also day one breakfast in Medina everyone being given a pager,guests backed up to the lift and all the way down to excursions desk. Person dishing out pagers did not sanitise her hands throughout. Tables set but people not being moved though. When asked why was told that she had not released the tables yet! total chaos. I refused to take pager and also refused to go back into the scrum,went and stood waiting to be called at the first desk inside, 30 minute wait,although we had not asked for a table for two. Do not blame the guests,the problems are within the crew,they are working and spreading because they have to.
