I was on the Disney Dream in September and they did have the extra staff holding the plates. Mine wore gloves. Yes it was awkward at first but it didn't prevent me from eating whatever I wanted. I talked to the manager and yes it has to do with health issues/health precautions. It has absolutely nothing to do with portion control. I eat my body weight in caviar each time and no one gives me a hard time.
Food is wasted whether someone puts it on their plate or not. Whatever is left on the buffet at the end of service is not saved for a later buffet. It is thrown away.
i'm not buying what the manager said. i think he/they may be being told to say this but it makes no sense. why would they do it for health reasons at palo but not in the main buffet? if you think about it, all the kids that are running around the main buffet, that would be where you would want the extra staff if it were just for that however that only happens when there is an outbreak. while there is still a the possibility of problems at palo, being all adults there is a lesser possibility. not to say all adults are clean or all children are dirty, just saying the odds are what they are.
