Express line joke for kids

My friend, the manager of a grocery store, nabbed a shoplifter in the act.

He was escorting the suspect to the office in the front of the store (near the cash registers), when the shoplifter broke from his grip and tried to run.

After a scuffle, my friend pinned him against the wall and looked up to see a number of surprised customers staring at him.

"Everything's fine, Folks," he reassured them. "This guy just tried to go through the express line with more than ten items."
