Participant mturk_agent_2's preferences:
value2issue: Low: Water
Medium: Firewood
High: Food
value2reason: Low: Often there is enough water in food to last us and fresh water can always be cleaned adequately.
Medium: Fires are high priority in camping, can be used for light, staying warm and cooking.
High: Probably the best weight to utility ratio, useful for emergencies or just for getting more joy out of the trip.

Negotiation dialogue:
mturk_agent_1: hi🙂

mturk_agent_2: Hello, I'm wondering if I can get extra food or firewood for my upcoming camping trip?

mturk_agent_1: First though, can you tell me your preferences ranking for the 3 items?

mturk_agent_2: I generally prefer food for emergencies and extra firewood for better fires and cooking.

mturk_agent_1: I think 3 water for me and 3 food for you is a good starting point

mturk_agent_2: I think that can work out, fresh water is easy to adequately clean in my experience.

mturk_agent_1: Now we're left with 3 firefood for 2 people☹️

mturk_agent_2: Feel free to take the leftover firewood, I think one extra unit is enough for us. 🙂

mturk_agent_1: wow that's generous of you

mturk_agent_2: No problem, we're all just trying to get the most out of our camping right? Haha.
