Negotiation dialogue:
mturk_agent_2: Hello I'm interested in obtaining more of the water and food, but don't need any extra firewood🙂

mturk_agent_1: Well I am really in the same position as you are. Suppose I take 2 waters and only 1 food? 

mturk_agent_2: I get really sweaty when I hike, so I really need to get at least 2 of the waters.

mturk_agent_1: My friend is joining me tomorrow so there will be two of us. I really need the extra water so we both can stay hydrated. You can have all the food and 2 of the firewood packs if I get 2 of the water packs. 🙂

mturk_agent_2: I understand, but I don't need any extra firewood.  You could have 2 food, 3 firewood, and 1 water?🙂

mturk_agent_1: Well I am going to have to think about this deal. Perhaps I can contact my friend and see if he can get some extra water. He is a big eater so the food may come in handy. 

mturk_agent_2: That would make things better for me.  

mturk_agent_1: Can I ask you why you need so much water for one person? 

mturk_agent_2: Hiking in the summer, I sweat a lot and I don't want to risk getting dehydrating and sick out in the woods.

mturk_agent_1: Well this might work out, I will agree to take 2 food, 3 firewood and 1 water. I think we will be fine because we are not going hiking. We are going to sit around campfire and catch up on old times. Good deal for both of us if you agree. 🙂
