Did I make the wrong decision?

Hi,

Yesterday I let my 6 (almost 7 year old) daughter go to the cinema with a couple of friends after school and their mum's.
However, I think I got the wrong end of the stick. When I was asked, I mentioned I needed to pick up my 3 year old and so the other mum said she could pick my eldest, take them to the cinema and if the little one wanted to come they could wait. I thought best not to make them wait so said go ahead and we will wait until the end of the movie to pick up oldest.

After the movie the two mum's seemed a little upset with me. I took it as I shouldn't have accepted the invite as my daughter apparently chatted a lot with one of the other girls and ended up wanting the loo half way through. With Covid, the seating was spread out a lot so they couldn't sit nearby to stop the talking.

I am not good at reading between the lines and making the right decision but I can't help but think maybe I shouldn't have let her go in the first place?

Thoughts please?

They meant they would pick up your eldest and look after her, whilst you collected your youngest. Then you and both your DC would go to the cinema with them, with you taking responsibility for both your DC and them looking after their own. It was a misunderstanding and paying for dinner was a kind way to apologise and make amends. I wouldn't worry too much OP.
