Hello, I would like to take all of the firewood and two of the water packages. You can take all of the food and the other water package. 
I am not a fan of that deal
That's alright. Do you have anything you need in particular? 
I need food and water
I need water too. One of mine has a leak.☹️
the temperature is 115 degrees F where I go,  If I don't have extra water I will not make it
That sounds awful 😮. Would you settle for you taking two of the water packages and leaving me one?
I guess if I can have 2 food and you can have 2 firewood
Some of my firewood is wet (and basically useless unless it dries in time). So how about 3 firewood and 1 water for me and you can have the rest. 
Ok that sounds good
