AITA for giving my friend’s girlfriend some of my fries after he said no?

I was out with my girlfriend, my friend Rick and his girlfriend Jane. Jane and my girlfriend both ordered chicken caesar wraps and side salad. Rick and I got shaved beef sandwiches with fries. When the food arrived, Jane asked Rick if she could have a few fries. Rick said no, if she wanted fries, she should have ordered fries. She said that she did not want an entire order of fries, she wanted a few.
I said she could have some of mine. She said thanks and took a few. I did not think anything of this interaction. After we left, Rick asked me why I gave into Jane’s little game. I said huh? And he said Jane loves to play the “no I don’t want fries ooh can I have some of yours” game and it pisses him off. I didn’t really know what to say. I said that I don’t think it’s weird to want a few fries versus a whole order and I could spare a few. Rick said it was a dick move to give his girl fries when he was obviously trying to make a point and get her to just order what she wants instead of taking from him.
(Sorry if you saw the original Nancy version that’s what I get for using fake names lol)
AITA?
