Can you help me solving this work place problem, by answering this questions. Thank you,

A cashier is working the night shift at a 24-hour grocery store. He notices that a customer is acting suspiciously and has a large bulge under her coat. The cashier thinks the customer is shoplifting. The cashier's responsibilities include preventing theft (loss prevention). Pretend that you are the cashier. Things to consider: Do you approach the customer? If so, how? What if the customer becomes aggressive? WHAT IS THE PROBLEM? What are the symptoms of the problem? What is the root cause of the problem the real problem? WHAT ARE THE POTENTIAL SOLUTIONS? Are there any factors that you need to consider when choosing a solution? (e.g. policies, procedures, etc.) What are the advantages and disadvantages of each possible solution? What are the consequences of each possible solution? WHAT IS THE BEST SOLUTION? Which solution is the best overall? Why? Choose a solution and act on it! DETERMINE HOW TO ACHIEVE THE BEST SOLUTION Think about what you will have to do to reach your solution. What resources might you need to use? IS THE PROBLEM SOLVED? Did the chosen solution solve the problem? If not, return to Step 1 to review the problem again. Try using a different approach.
