Another approach is to lift the bowl to one’s mouth and use one’s tongue to grab the chips. The shape of the bowl affects how easy this is, and when it’s mostly empty one may tilt the bowl and make as if to drink from it. Of course, some may think this looks uncivilized.
Another approach is to use three fingers to eat, and two fingers to type. (Typing with one hand becomes much faster when you can use even one finger from the other hand.) This works less well when reaching into a bag—hard to prevent the clean fingers from touching anything.
