There was trays in buffet on Britannia last month april 16th cruise also saw tea and coffee trolley waitress but she was manly helping disabled passengers. We used her once as my wife is wheel chair user, I usually get hers and mine, but as they were out of cups at the station, I asked her for teas as she had about a dozen on the trolley so I did not have to wait for cups. I think if they stop the trays I will be up and down more often then my usually 3.
