Not only is this a gross form of conduct, but also a case of an absent brain in the form of basic sanitary knowledge especially one who has been trained to be qualified to serve food/beverage in a premium cabin. I can care less if she had washed her hands 10x prior to serving the pax because you just don't dip your bare hands into the tray making contact with the food portion. I can only imagine if she made finger contact with the omlette portion while she was removing the ham and potential germs from her nails penetrated into the egg dish. Even back in high school, the lunch lady serving sandwich wore gloves in putting the lettuces, ham and other ingredients into the bread.

I presume since it was breakfast omlette/congee selections, it was on the YVR-HKG sector in that this FA is highly to be a YVR based. Not sure these days if HK based crews are still rostered on the YVR flights.
