Participant mturk_agent_2's preferences:
value2issue: Low: Food
Medium: Firewood
High: Water
value2reason: Low: Although food is a requirement, its my belief that we could get by with less of it than the other items.  We know we're not going to be gone that long and our bodies have the emergency 'stores' we would need if it came down to it.
Medium: We need the firewood to keep the campsite warm and, of course, to cook food.  Its also useful to provide light and, if we were to somehow get lost, to use for smoke signals to indicate our location to the rescue parties involved.
High: One can never have enough water.. its quite valuable.  I never know when we also might need additional for cooking or cleaning or an unforeseen circumstance.

Negotiation dialogue:
mturk_agent_1: hy thats my offer

mturk_agent_2: Hi there.. I'm sorry, I didn't see your offer as it doesn't show it for 10 messages, I believe.  So, here's the situation.. I think I can get by with less firewood as I'm a Floridian and prefer it cooler anyway.. also the food is not a huge thing for me as we can catch / improvise around the campsite - but I'm definitely interested in as much water as possible.. both for cooking and cleaning purposes, as well as drinking, of course.  🙂

mturk_agent_1: okay so what do you suggest

mturk_agent_2: Well, I recognize you're gonna need water too.. so I'd love to take 2 of them, giving you one and I'm totally ok with going 1 on the firewood and one on the food.. that way we all ensure we have enough.. you're making out a bit better in quantity that way but I think its best for both of us 🙂

mturk_agent_1: i botttle of water for a can of food and 2 firewoods

mturk_agent_2: Yeah, sorry, that's not going to work out for me.  I'm going to need at least 2 bottles of water, 1 food packet, and one firewood.. again, this does leave you with two each on the food and the firewood, which are both very important things for this camping trip!

mturk_agent_1: but thats the only offer im willing to give

mturk_agent_2: Well then unfortunately I think we're gonna have to walk away from this and neither of us gets anything we could both use.. that's unfortunate and I'm sorry to see it end in such a less than magnanimous fashion ☹️

mturk_agent_1: you need water and i need food so unless we do 1 food  to 1water is tht okay

mturk_agent_2: I'll tell you what I'm willing to do.. I can't really budge on the water.. BUT.. I could do something where I take 2 water, and only one firewood, but two food.. does that work for you?

mturk_agent_1: so if i were to  give you water what would i get ?

mturk_agent_2: You'd be getting 1 water, 2 firewood, and 1 food

mturk_agent_1: how much food are you willing to offer for water

mturk_agent_2: We can go back to my original offer which was honestly more generous.. I get 2 Water, 1 Firewood, 1 food.. you get 1 water, 2 firewood, 2 food.. its honestly a better deal for you 🙂

mturk_agent_1: no its not i give you i water i get 1 food and 1 firewood

mturk_agent_2: We only have 3 of each to divide up.. so yes, you're going to have to give me one more on an item.. but in exchange I'm giving you 1 more on two different items.  I'm getting 4 items in total, you're getting 5.. - You're essentially netting 11% more 'items' than I am in this deal. 

mturk_agent_1: thats the point as you need water so badly

mturk_agent_2: Correct.. I do.. but if you're not willing to budge on this where you're still netting more overall value I understand - I'm bummed but I understand.

mturk_agent_1: im contented with  what i have but im willing to trade as yu need more water so i need t make a profit

mturk_agent_2: That's unfortunate then as instead of making a tiny bit less of a profit now you're not going to make any because you would rather give up the deal.  Also, if you do the math, you'll see that I'm actually benefiting you here - I understand, though.  I can put through the offer and hope you change your mind so we both benefit.

mturk_agent_1: im fine with that
