Negotiation dialogue:
mturk_agent_1: Hello fellow camper! 🙂 How are you today?

mturk_agent_2: I'm doing okay! Kind of a slow day on MTurk, how are you?

mturk_agent_1: I am doing quite well actually. What supplies do you need?

mturk_agent_2: Firewood would be great! 

mturk_agent_1: I agree that it would be great. I didn't bring an axe though. So it is hard for me to get anymore.

mturk_agent_2: Ah I see, do you have food then?

mturk_agent_1: I do have food. What exactly are you thinking?

mturk_agent_2: Well, what is it that you're looking for?

mturk_agent_1: I need extra firewood and a little food. Since I didn't bring my axe, as I mentioned earlier, it is hard for me to get extra wood. I would like some food because I have an extra guest.

mturk_agent_2: Okay, since firewood is a higher value item than food, I could trade you 2 firewood for 3 food in return?

mturk_agent_1: If you get all the food I would need all the water to barter with someone else.

mturk_agent_2: How about one food and two water then, in exchange for 2 firewood.
