Negotiation dialogue:
mturk_agent_1: Hi there! I was looking for 3 extra packages of food and 3 packages of firewood.

mturk_agent_2: We can work a deal out. How's your day? 🙂

mturk_agent_1: It's good, thank you 🙂 Which package is the most important for you to have on your trip do you think?

mturk_agent_2: That would be firewood. Even though is really hot there, it gets cold at night. How's the weather for you? 🙂

mturk_agent_1: Ah yes, you'll definitely need some extra wood then! It's also pretty cold here, especially during the night. But I would definitely be willing to let you take 2 firewood in exchange for 3 food. We have a lot of people going and will be out in the middle of nowhere.

mturk_agent_2: We can definitely work something out. I'll be sure it'll benefit you more than me. 🙂

mturk_agent_1: Oh, well that's really nice of you. What do you propose?

mturk_agent_2: You'll get 3 food and 2 water, and I'll take 3 firewood and 1 water. 🙂

mturk_agent_1: Hmm, I think that could definitely work! Appreciate it 🙂

mturk_agent_2: Sound great 🙂
