Medium: Firewood
High: Food
value2reason: Low: I want to climb at least one mountain a day, so I'll need more water than the basic supplies included.
Medium: I only brought a summer sleeping back, but it is much colder here than I was expecting and I'll need a bigger fire.
High: Brought my dog with me, but the basic supplies didn't include dog food - I'll need more "people" food for him.

Negotiation dialogue:
mturk_agent_2: I am looking forward to this camping trip but I am concerned with not having enough water.

mturk_agent_1: Oh, I can understand, I'm worried about food 😡.

mturk_agent_2: I could agree to let you have more food in exchange for me having more water.

mturk_agent_1: That sounds like a fair plan. I wish they had consulted us before sending everyone the same basic package, don't you? 

mturk_agent_2: That would have been really helpful.  🙂 As far as the firewood, I could use more of that also. I tend to get cold easily.

mturk_agent_1: I'm flexible on that, though I made the mistake of bringing a summer sleeping back to the mountains. A bit chilly, lol.

mturk_agent_2: So how does 2 waters for me and 1 for you, 2 firewoods for me and 1 for you, and 2 foods for you and 1 for me sound?

mturk_agent_1: Hmm, if you get 2 firewoods, then I'll need all 3 foods as I'll have to search around for extra wood. Plus I was hoping to give some treats to my dog and they didn't include any in the supplies!

mturk_agent_2: I realize with the odd number of extra supplies, there is no way to distribute equally.  I can't give up any extra food incase of emergency. Sorry.

mturk_agent_1: Then I'll definitely need 2 food, 2 firewood, and just one water.

mturk_agent_2: I really need the extra water as I get dehydrated easily and I told you already about being cold.  I'm not trying to be disagreeable. These are things I really have to have.

mturk_agent_1: I understand, but it is the same here. If dehydration is your biggest worry I can do 3 foods for me, and all three waters for you, with 2 wood for me.

mturk_agent_2: I can't let extra food go.  I'm going to have to have 2 waters, 2 firewoods and 1 food.  This is where I'm at.

mturk_agent_1: Oh, dear, I'm afraid this might be a failed trip then. I really can't agree to that. Too bad.

mturk_agent_2: Sorry to hear that.  We were so close.

mturk_agent_1: Yeah, too bad you caught me on a bad week - I got cheated out of a work bonus on Monday and now I'm not feeling very friendly/amenable. Bad luck for both of us, sorry!
