Negotiation dialogue:
mturk_agent_1: I would like to ask for 3 firewood, 1 water and 0 food. I will be in an area where no extra wood will be available and I need the wood to cook all the food that I will already have.

mturk_agent_2: I understand where you're coming from but I'm afraid that is not acceptable.  My family's comfort is my top priority and I will be needing at least 2 firewoods to make sure they are kept warm.  I would also request some extra water. 

mturk_agent_1: I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.

mturk_agent_2: It seems we both have a big need for firewood. 😮 If you insist on 2 firewood, then I insist on getting 2 water AND 2 food along with 1 firewood.

mturk_agent_1: I insist on 2 firewood 🙂. I would be happy to let you have 2 water. Are you sure you need 2 food?

mturk_agent_2: Yes. If I'm letting you have more firewood (of which I would like to have more) then I'm going to need more of the other supplies. 🙂

mturk_agent_1: I would be ok with this situation.

mturk_agent_2: So I would get 2 water, 2 food and 1 firewood?

mturk_agent_1: Yes that is what would work best for me.

mturk_agent_2: Then I think we have a deal.
