Really, no one should be drinking high sugar drinks. Even stuff like juice should be a once in a while thing. I'm as guilty of it as almost everyone else, I admit. Hard to break that sugar addiction.
Much of the world does, unfortunately. Our bodies crave sugar because we needed the energy to do our hunting back when the species evolved... but we didn't need or have access to a lot of it. Still, we crave it. And companies that make processed food are almost certainly aware of that fact since they employ food scientists and psychologists. They take advantage of it.
Even worse it's coconut water. That's okay in a normal market. But this might be the only "clean" water within a day's travel in an emergency like this. The problem is there are people with coconut allergies and sensitivities. So for them he's effectively sent poison. Furthermore, not everyone in a disaster zone needs rehydration all the time. This is why aid organizations don't even send pre-mixed drinks. It's the powder packets.
Literally everything about this is wrong. I wouldn't be surprised to learn they just unloaded the trailer in a random parking lot inside the declared zone and ran away.
