<human>: Can you provide a brief overview of the text?

So a little background to the question, me [F] and my SO [M] wanted to order takeout 2 days ago from a restaurant that we go to frequently. So he told me he just wanted a chicken sandwich, sandwich only with no sides, and i wanted some fries. And usually the sides are a choice of salad or fries. 

So when i went to order him the chicken sandwich the lady at the counter said the sides are included so might as well order something, so I ordered myself a salad (since I already had fries and since he mentioned when ordering he wanted the sandwich only).

However when we went back home he tried to claim possession of my salad, even though he made it very clear in the beginning he didn't want the sides.

So who's salad is it?
<bot>: SO didn't want any sides with his sandwich so i ordered his side for myself. Can he claim it or is it mine?
