Negotiation dialogue:
mturk_agent_1: Hello, I'd like to bring three packages of firewood because I'll be making tons of BBQ for the camping trip.

mturk_agent_2: Can I get 3 packages of food?

mturk_agent_1: What do you need it for?

mturk_agent_2: I would like some extra food in case I get hungry.

mturk_agent_1: Okay that sounds ok, I can do without the food. I also need two packages of water because it will be very hot out.

mturk_agent_2: I can give you 2 packages of water.  I think there is plenty of water, so I do not need extra water.🙂

mturk_agent_1: What are you going to use your water for?  And thank you.

mturk_agent_2: In case I do no feel like going to other places to get water.  It would be nice to have extra water.

mturk_agent_1: I see, and do you have a way to bring the water with you?

mturk_agent_2: I'll probably just put the water in one of my bags.
