Do you typically bring enough for the entire party? Or just enough for some?
This is one of the many reasons that I decline (or at least try to) when people offer to bring a dish. First of all, as many on CH will agree the social dance goes like this:
We'd love to come for dinner, thanks for inviting us. What can we bring?
I'm so glad you're coming, just bring yourselves!
Then you turn up with wine for the hostess or a nice little gift.
But sometimes the host will accept or sometimes the guest will insist... so you've got a situation brewing.
As the hostess, I serve enough food for all of my guests. Running out of something is not an option even if that means I have double the food that people could possibly consume. I am certainly not going to make only enough of one dish for some guests to consume and think 'tough luck' to the rest.
When a hostess accepts my 'What can we bring' I bring enough for everyone to eat it for breakfast, lunch, dinner and a midnight snack. Otherwise I might put the hostess in an embarrassing situation. But that is certainly not the case with everyone.
If someone comes to your home with a dish that is too small to feed the group, do you still put it out? If not, what do you do with it?
