value2issue: Low: Food
Medium: Firewood
High: Water
value2reason: Low: I might get hungry on the trip and need additional food.
Medium: More firewood is helpful because I'm not very good at starting fires -- this would give me more leeway to get a fire going and keep it going.
High: I have a medical condition where toxins build up in my kidneys unless I drink a lot of water every day. I normally drink about a gallon.

value2issue: Low: Water
Medium: Food
High: Firewood
value2reason: Low: Clean water will be hard to come by and having it available will be lifesaving. 
Medium: Since I will be staying for more time I will need more food.  
High: I plan to stay a few nights and will need to keep the fire going to keep wildlife at bay.

Negotiation dialogue:
mturk_agent_1: Hi! I'm most interested in water. What are you hoping to get today?

mturk_agent_2: Hello I'm most interested in the firewood and think we can come to an agreement on the water. 

mturk_agent_1: 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.

mturk_agent_2: 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.

mturk_agent_1: 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.

mturk_agent_2: 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?

mturk_agent_1: It's a pretty big priority but I would be willing to negotiate on it. 🙂

mturk_agent_2: Since I compromised on the water I think it would be fair for me to get 2 food rations. 

mturk_agent_1: Okay so I get 3 waters and 1 food, you get 3 firewoods and 2 food?

mturk_agent_2: Yes I'm okay with that deal.
