Art and Chris arrived at the café a short time after Ystris and Micah sat down. They had apparently rushed to get their task done since they breathed a little heavier than usual from running back and forth between Pride's Mansion and the town.
They entered the café curious about the situation and were more than a little surprised to see the others and, Ystris sitting down to enjoy a luxurious feast spread out across several tables. They knew it wasn't the right time to be taking it easy and eating like it was the first time they had tasted food since birth.
But the allure of the food got to Art and Chris, so before they could even voice any protests or doubts, they followed Micah's inviting gesture and took their seats. If they hesitated too long, the others would get to all the food before they could get any.
If they were going to eat, they might as well decide to do it quickly and get as much of the food as possible.
