Negotiation dialogue:
mturk_agent_1: Hello, I am all packed and ready for my camping trip! I am looking forward to spending some time in the great outdoors!

mturk_agent_2: Me too. I love camping. We are going hiking and fishing today. So excited.

mturk_agent_1: I could use some more firewood. Are you short on any supplies?

mturk_agent_2: Water please. We will drink a lot of water since the weather is very hot now. 

mturk_agent_1: How about you take 2 water from the extra supplies and I could take 2 firewood?

mturk_agent_2: Sounds like a good deal. I just need 1 firewood to make camp fire. Which item do you prefer the least?

mturk_agent_1: I am least concerned about food.

mturk_agent_2: So can I get 2 then? 🙂

mturk_agent_1: Sure. So you will take 2 water, 2 food, and 1 firewood?

mturk_agent_2: Fair deal, I think. We have enough food so we don't need to cook anything. I will tell the kids no smores tonight.
