Negotiation dialogue:
mturk_agent_1: Hello!

mturk_agent_2: Hello

mturk_agent_1: On my upcoming trip, I would like some extra food and water for my family.

mturk_agent_2: Ok. I would like to have some extra firewood.

mturk_agent_1: Do you have a preference between food and water?

mturk_agent_2: I would like water more than food. 

mturk_agent_1: How many wood do you think you need?

mturk_agent_2: I would like 2 of the firewood. What do you think? 

mturk_agent_1: I don't need wood as I am usually warm so I think we can work out a deal. I like to have more water and I usually get thirsty.

mturk_agent_2: That sounds good to me. 🙂 I think we can make a good deal.

mturk_agent_1: I can give you 3 wood packages if I can get 3 water and 2 food. So you will receive 3 wood and 1 food. What do you think?

mturk_agent_2: I would like 2 wood, 1 water and 1 food. You would get 1 wood, 2 water and 2 food.

mturk_agent_1: I don't need any wood. Do you have any alternatives?
