Went to visit my gf in college once a few hours away. On the way back I put every penny I had into my gas tank in hopes it would be enough and it barely was. While at the gas station I mixed some ketchup packets, salt, and hot water for “tomato soup” because it was all free.
Not good. Just watery ketchup. But it was a hell of a lot better than nothing. It did help that I snagged a few packs of crackers for texture.
