Hi! I'm most interested in water. What are you hoping to get today?
Hello I'm most interested in the firewood and think we can come to an agreement on the water. 
Okay. What if I take all the water and you take the firewood? Then we can split the food, I'll take 2 and you take 1.
I think it would probably be best if we split it by you getting 2 waters and 1 firewood that way we both have at least one of everything.
Is there a reason you need extra water above the basic supplies we already have? I have a kidney disorder where I have to drink a ton of water every day.
Okay if you need the water for that I can go with 3 firewood for me and three waters for you but how much of a priority is food for you?
It's a pretty big priority but I would be willing to negotiate on it. 🙂
Since I compromised on the water I think it would be fair for me to get 2 food rations. 
Okay so I get 3 waters and 1 food, you get 3 firewoods and 2 food?
Yes I'm okay with that deal.
