To think this is rude?

I have just catered single handedly for 12 for two days. It's been hard, hard work. Three families and no offered to do the washing up/help with cooking (apart from my husband). I work full time for what is is worth- including Christmas Eve and back to work tomorrow. So pretty shattered. The other wives and one BIL don't work at all.
I really pushed the boat out as we missed out last year.
Probably spent >£600 in food and alcohol.
My sister in law asked what she could bring- I suggested some cheeses and crackers for Boxing Day. She brought 4-5 cheeses and a bottle of port.
She left this morning. I have just noticed she has taken all the remnants of cheese from the fridge and 1/2bottle of port home with her.
I think this is bloody rude my husband less so.
Who is being unreasonable?

It sounds like the OP generously hosted and then graciously set aside her guests lack of help in order to ensure her MIL had a lovely day, which was a kind thing to do.

The port and cheese was then the straw that broke the camels back.

I’d definitely send the text suggested above: maybe even adding in an

“exhausted! Just sat down after finally putting house back together, but DH can’t find the port. Any ideas where it went? I think MIL had a lovely day which is what counts but now I need to relax with a delicious plate of cheese!”

Yeah all these people saying oh just instruct cousin Noah to clear the plates or whatever, it often doesn't work like that in real life.
