Mr. Publix vs. the "Shark"

Mr. Publix was tired. He had just woken up, and was working at 7:00 on a Saturday morning. He tried his best to keep a good attitude, and at the moment, it was working. That changed soon. A short, old, round man stepped into the room, with a plastic, but maniacal smile. He went into the break room to punch in. He came back out of the break room with a Miami Dolphin's shirt on, and still wearing that smile.
He went to a superior, and she gave him an assignment. He began to take plastic bags from boxes, and store them in plastic bins underneath the bagger platform at the end of the check-out aisle. He looked over at Mr. Publix, and read his name tag aloud.
"Mr. Publix, would you take these and put them in the bins?"
Mr. Publix looked over at the man, and politely did the job the best he could, not denying the man a favor. Suddenly the man sounded angry.
"No, no." He walked over to Mr. Publix, and told him how to do it.
Mr. Publix did his best, and this time with some more knowledge on the task at hand. However, no matter how Mr. Publix did the job, he couldn't do it right for this man. Mr. Publix stopped doing the job, and waited for the man to walk somewhere else. He looked over at an agent only one rank above him. A rank labeled "cashier." Her name was Veronica.
Mr. Publix leaned over the counter, and asked. "What is that guy's name, and what is his rank?"
Veronica looked at Mr. Publix, and said "We call him the 'Shark.' He's just a bagger like you. He picks on the new people, trying to get them to do jobs his superior asks him to do. Don't take orders from him. He's as much of a rat as he is a shark as well. If he sees you do something wrong, he'll run right to Andy, and tell him. Don't do what he tells you. He is not your superior. The only reason we keep him is because he can wear that smile all day to make our customers feel welcome."
Drat! Just when Mr. Publix thought all employees were good. That fantasy just had to be ruined, didn't it? Now Mr. Publix was perplexed. He had had trouble with this "Shark" guy before. This was not the first time. How to handle it though? At first, Mr. Publix thought he should heroically punch the old man in the jaw. After all, the "Shark" could end up a worse nemesis than that runaway shopping cart. He suddenly realized that an action so cruel as that would not be so heroic. He also realized that the "Shark" was not his enemy. The pain and laziness the "Shark" harbored was his worst enemy. That's right, even worse than cart. He knew from his readings of the Bible that the only thing that can cure him of that is God's grace. The only way for humans to make a man open to seeing God's grace is to be "...wise as a serpent, and gentle as a dove..." Act just as Jesus would. That would require a lot of heroic effort. With God's help, Mr. Publix can do it. He can cure the "Shark."
