The salesclerk overheard a man speaking on the phone who was obviously seeking a job.
"Oh," he said, "You don't need a new manager. You have a manager who is already doing the job? You don't have another opening," he seemed to be asking again and again.
As he walked away from the phone booth, the salesclerk sympathetically said, "I couldn't help overhearing…I'm sorry you didn't get the job."
"Oh," the young man said, "I already have that job. I just phone in every now and then to find out how I'm doing."
