Fattening others

When out with a group of friends or a friend, does anyone intentionally overeat so that people don't feel uncomfortable eating more than they usually would?

If Wolf is going back for more, maybe I will too...

Maybe you offer to finish what they have left...

Now when I think about it, I might kinda do that naturally/unintentionally.

But maybe only few times I have gone for example to get more dessert when someone else has been thinking about having more. And basically the purpose behind that has been engouraging them, but also of course having a little something delicious for myself too.
