Negotiation dialogue:
mturk_agent_2: hi there🙂

mturk_agent_1: Hello. I'm going camping and am in need of extra supplies. I hope we can strike a deal. 🙂

mturk_agent_2: Me too.  I need water due to a blood pressure condition that leaves me at high risk of having a stroke when out and about ☹️

mturk_agent_1: Oh goodness. I am in much need of water too. Are you sure that you should be out camping? Maybe a local hotel would be better for your condition.

mturk_agent_2: I am along to spend at least some quality time with my grand children, even if it might be my last.  They are also ravenously hungry.  They grow up fast!

mturk_agent_1: I have more wiggle room on the food, but not so much that I can give it all to you. I do have much need for firewood.

mturk_agent_2: That is okay, we brought a lot of blankets.   Is your priority firewood?

mturk_agent_1: My priorities are water, firewood, then food. I assume yours are water, food, then firewood last?

mturk_agent_2: That is correct. You can have all of the firewood

mturk_agent_1: Okay. What do you think of this split then? You will get 2 water, 0 firewood, and 2 food. Since I will get only one of my top priority item, but you will get two, I will have 5 items to your 4.
