The first example is found in the first paragraph, when the grandmother says:
"Here this fellow that calls himself The Misfit is aloose from the Federal Pen and headed toward Florida and you read here what it says he did to these people. Just you read it. I wouldn't take my children in any direction with a criminal like that aloose in it. I couldn't answer to my conscience if I did."
They do run into him, and the children are along, and it isn't good.
A second example comes a bit later, in this exchange:
Red Sam came in and told his wife to quit lounging on the counter and hurry up with these people's order. His khaki trousers reached just to his hip bones and his stomach hung over them like a sack of meal swaying under his shirt. He came over and sat down at a table nearby and let out a combination sigh and yodel. "You can't win," he said. "You can't win," and he wiped his sweating red face off with a gray handkerchief. "These days you don't know who to trust," he said. "Ain't that the truth?"
"People are certainly not nice like they used to be," said the grandmother.
They aren't, as the Misfit shows.
