Context: 'Hello, I'm in need of some extra food for my trip.  I just checked and some of my food is past the expiration date.' 'Hi friend! How are you. Food is a non negotiable for me. We currently don't have enough for our trip.' 'Everything is negotiable 🙂 but if you absolutely can't budge on the food then I will need some extra firewood and water to make up for it.'
Utterance: 'We cannot budge at all on food. But are more then happy to give up all the extra fire wood for all the food. '
