It shows that you are carb sensitive so it is a good lesson for the future to be careful about having extras.
You are not hungry; this is not physical hunger (which comes on gradually over a few hours). You are having classic emotional/psychological hunger. So you can "choose" not to have chips or "choose" to have them, as already said you don't physically need them.
