As they were running toward Ryder, just one thought was running through the minds of each of them, 'So we'll finally be able to eat something?'.
They reached where Ryder was standing and glanced into the grocery store, and they confirmed what Ryder was saying. According to what they were seeing, this grocery store was almost emptied by a person or people. And they must be those people going around breaking down grocery stores...most likely.
This grocery store was filled with lots of foodstuffs before according to what they discern, but most of the foods were taken and only a few were left. What foods were they seeing currently? All snacks. They could see some packs of chips, some doughnuts, egg rolls, and about three soft drinks.
