Negotiation dialogue:
mturk_agent_2: hello

mturk_agent_1: Hey, how are you?

mturk_agent_2: I am doing good. Thanks. Which item do you need the most?

mturk_agent_1: I was thinking firewood, because the most fun I have camping is roasting marshmellows and hanging out around there. How about you?

mturk_agent_2: Oh hmm. I really need extra firewood because I forgot to bring a sleeping bag. I will be freezing to death at night. ☹️

mturk_agent_1: Okay, well tell me what you need the least of, if you don't mind.

mturk_agent_2: You can have all of the water if you let me have all of the firewood.

mturk_agent_1: hmm, here's what I'm willing to do. I will take all the water, one firewood and one food.

mturk_agent_2: That doesn't sound fair to me.

mturk_agent_1: Ok, what would you counter offer with?

mturk_agent_2: I would like all 3 packages of firewood and 1 package of food. You can have the rest.

mturk_agent_1: Well, I would like at least one firewood, it is the thing I most need.

mturk_agent_2: But you need firewood for leisure, whereas I need firewood for survival.

mturk_agent_1: Well it will keep us warm at night, too. I am very keen on at least one firewood for myself. 

mturk_agent_2: Ok. How about I take 2 firewood and all 3 food? You can have the rest.

mturk_agent_1: Can I get at least one food?

mturk_agent_2: Would you be willing to trade that for one water? So I take 2 firewood, 2 food, and 1 water?
