In last nights episodes they had a drop for 12 god damn cantaloupes. Are they serious? They wasted their gas and time for 12 cantaloupes? Then they came back again for 1 more the next day.
Maybe space out the drops so the delivery is more than 12 cantaloupes.
Maybe Negan really, really, really, really likes cantaloupes. A lot.
Like you said, though, it would have made more sense if it there were a variety of items in the tribute, but the sticking point was that it was short one cantaloupe. In addition to the time and gas, it didn't make much sense for both sides to send full crews for such a small exchange. Even if everything went smoothly, the Kingdom had 7 people, including their leader, out on a mission to deliver 12 pieces of fruit.
I think this point can be explained by the shock of the events and only a day passing between the meetings, but shouldn't someone from the Kingdom group been curious about how they ended up with only 11 cantaloupes? They had 12 when they left, so one must have disappeared on the trip. Either a stranger snuck up and took just one during the shopping cart delay, or someone in their group took one. I can accept, though, that these people have been through a lot, live in a crazy time and just lost a friend, so giving the situation the CSI treatment may not have been their immediate priority.
