Negotiation dialogue:
mturk_agent_1: Hi there, and sincerely wish you can exchange some needed items with me.

mturk_agent_2: Hello! I'm heading out on a camping trip myself, and also need some provisions. I will be enjoying the fresh air in a cold climate away from any bodies of water. Also, I will be working with a refugee camp while I'm there, providing solace and counsel to poor souls in need. So you see how critical it is that my trip is successful. I believe we can work out a deal though. I recommend that I have 3 water, 2 firewood and 2 food.

mturk_agent_1: From my side, our family of 7 are out on a first time adventure and just discovered unfortunately we were inadequately prepared. Thus, all items are quite needed especially the food and water as we have exhausted all the initial basics.

mturk_agent_2: I see, but can you reschedule your camping trip for later? I have great needs for the water. You recall I will be camping away from all large bodies of water and will need to pack it all in. I might be able to negotiate on the food.

mturk_agent_1: Unfortunately it is impossible as we are already on site compared to you about to head out. 

mturk_agent_2: I see. You are a victim of poor planning. Whereas the refugees I attend to are the victims of greed, malice and human suffering. What are you proposing?

mturk_agent_1: How about I take 2 packs of water, 2 packs of food and 1 firewood

mturk_agent_2: Impossible. I will need to cancel the trip altogether.

mturk_agent_1: How about I take 2 packs of water while retain your initial request for food and firewood?

mturk_agent_2: I cannot allow any water. As I mentioned we will be camping away from all bodies of water and cannot negotiate on that item. I need 3 water, or else I will need to cancel the trip. We might be able to negotiate on the food though.

mturk_agent_1: I need to have at least a pack of water. How about 1 water, 3 firewood and 1 food?

mturk_agent_2: Okay. I fear some of us may die of thirst, but I will give you 1 water. I can't agree to those terms though. I can give you 1 water 1 firewood and 2 food. That is my final offer though.

mturk_agent_1: I am sorry, these terms are not favorable for me.

mturk_agent_2: Walk-Away
