This is a problem that plagues me. If the dip runs out first I can’t enjoy the remaining chips, and if the chips run out first I feel like I missed out on having extra dip. Only once have I ever finished the chips and dip simultaneously. I later told my mother about it and she wept tears of joy.
However, if you’re at a party then the efficient chip-dip ratio is irrelevant and a new strategy comes into play: how much dip you can physically load your chip up with. It’s brutal out there.
