Who gets the leftovers?

I had a small outdoor party for my sons second birthday last weekend

At the end of the party, there were some leftovers, not much, a few sandwiches and fried chicken, and ribs and pasta

My husband and I catered the party, and we paid for everything

So I went in the kitchen to clean up, and my mother in law was packing up the left overs for her two daughters to take home. Both of my sister in laws have families, so it was enough for them to eat for dinner the next day.

It was fine, I kind of assumed she would do that because anytime I’ve had a party at my house, she divided the left overs so everyone could take some home. But I was pissed off, because my brothers gf was there, and she has 2 kids, and she didn’t get anything. I told my mother in law that she might want some too, and her response was that “there’s not really much left”

I mean, it wouldn’t have been much anyway, but I’m not sure why she decided who gets what and gave it to her daughters, when she didn’t pay for it, and it wasn’t at her house.

My husband doesn’t think it’s a big deal, it was just some sandwiches and chicken, but I’m kind of pissed off about it. She always just has to take over everything. I’m let it go, because my mother in law just does whatever she wants anyway, and has always just walked all over me, so saying anything wouldn’t have gotten anywhere. I didn’t mind sending everyone home with food, but my brother and his gf should have been included
