... in our neck of the woods, eating at parties is to be enjoyed...and there is always plenty of food. So what about quotas. The family always orders more than enough for everyone... AND the Host will actually tell everyone, to go ahead and to eat more. Because, they don't want to have tons of leftovers to then take home and they don't have room in their fridge.
OR, if there are leftovers, the Host makes take home plates for EVERYONE, with the food & leftovers, for the guests to then take home.
Again, because the Host does not want to take all the left overs home, and then there is no room at home for it in their fridge. Then, that will be money AND food... wasted.
But sure, if you are at a party in which there is hardly any food, then common sense is, to politely not take too much and hold back.
Not everyone, can properly gauge, how much food to order.
Or they are on a budget.
But per the party you attended and describe, there WAS plenty of food.
So, to me, its fine if your Husband and daughter ate more.
Why not.
Again, in my neck of the woods, people EAT at the parties. They eat. There is ample food. And the Hosts TELL the guests, to eat and not hold back.
In fact, if there are leftovers... that is seen as people didn't like the food.
And then that is rude.
Sure, and my kids/my family or anyone, is usually taught about politely taking not much food. If there is hardly enough food at a party. But then they can have seconds, too. Once everyone has gotten their plates.
