It's a Baptist church so no one else probably wants the front row. They don't call them "Backrow Baptists" for nothing. (I grew up in a Baptist church ((thankfully not as fundie as this one but still bad)) and it's true about the back rows.)
The difference is that you ate food from the food court. Jill brought in outside food so she was just using the space. And do those kids get anything besides Little Caesar's?
