Quite prepared to be told I'm being precious however....
DD2 is 4 and in reception. She has school dinners. Since starting school her table manners at home have got progressively worse - eating with her mouth open, elbows sticking out, slurping etc. Friends we invite home appear to eat in this unpleasant way too.
DD1 aged 7 says this is one of the reasons she has packed lunch so she doesn't have to sit with other children who eat with bad manners. It is noticeable that DD1's friends usually have awful table manners too.
I remember table manners being a huge deal at my primary school 30 odd years ago but I'm an old gimmer and went to a crazy church school which wasn't much like a normal primary.
Guess we just need quietly to reinforce nice eating at home but do schools not comment on table manners or encourage kids to eat nicely any more?
