Negotiation dialogue:
mturk_agent_1: Hi 🙂 My friends and I are going to go camping and we'd like to invite you to come with us for a bonfire.

mturk_agent_2: I appreciate the invitation but I am going camping on my own with my friend at that time. And we will be in a different location. ☹️

mturk_agent_1: OK, we understand. We'll have our grandpa with us and he needs all 3 waters for his rheumatoid arthritis, and since his bones get cold we'll need all 3 firewood. Is this OK?

mturk_agent_2: No, that is not okay. 

mturk_agent_1: You will receive all three foods. We will take no less than 2 firewood and three waters.

mturk_agent_2: I don't need food. I have canned goods. I need firewood and water too. We will be in a tundra and will freeze to death without fire. And all the water in the area is frozen. I will take all the firewood and 1 water. You can have all the food and 2 waters. 

mturk_agent_1: No. We will take 1 firewood. All the food. 2 waters.

mturk_agent_2: There are 9 items. That means one person gets 4 things and one person gets 5 things. Not six and three. Because you are being greedy, you can take 1 fire and all the food. I'll take 2 firewoods and all the water.
