In chapter six what does it mean whan Bud's pretend dad says thayou would expect that they come down here and tell the truth.

Suddenly a hand clamps down on his shoulder. A man in overalls calls him “Clarence” and asks what took him so long. Bud is confused. The man points to a woman with two children and tells him to get in line with his family. Bud catches on and joins them. Others in line aren’t happy but they see how big his pretend father is and say nothing.
