I grew up with meals being plated in the kitchen by whoever cooked and then brought out to the table. DH grew up in the Netherlands and always did "family-style" where serving dishes are brought out to the table and everyone helps themselves.
AIBU to think family-style is stupid? It causes food waste because you have to make extra because can't predict how much people will take. & it causes over-eating because people keep eating until they're stuffed rather than until their plate is empty. & it wastes time because you need to carry more to the dining room and back (sometimes when we have breakfast at the in-laws there'll be 30 different things on the table!)
