(I am cashier at a pet store. I see a man walk into the store, pick up a large and expensive coffee table book on show dogs, and get in my line. My manager has warned me, and shown me a picture of this man. He tries to convince cashiers to give him a refund for items he has just stolen. I immediately page my manager, who, unbeknownst to me, is tied up with a minor medical emergency in the back of the store.)

Thief: “I want to return this item.”

Me: “Do you have a receipt?”

Thief: “No.”

Me: “I’m very sorry, sir. Without a receipt, I cannot give you a refund.”

Thief: “Give me a refund.”

Me: “Sir, I watched you pick that book up when you came in. I know you did not buy it.”

Thief: “Give me the f****** money, or I’ll kick your a**.”

(Most of the customers in my line start backing away.)

Me: “Sir, I cannot give you any money, and if you leave with that item I will call the police. Please leave the store.”

Thief: “You little a**-hole!”

(The thief grabs the front of my shirt, and rears his arm back to punch me. I throw my arms up to shield my face. Out of the corner of my eye, I see a flash of movement. The next thing I see is a spatter of blood on my counter, and the man out cold on the floor with a bloody nose. My manager, with a paramedic from the earlier emergency, walks up.)

Manager: “What the heck just happened?”

(As I tell my story, an assistant manager calls the police, opens another line, and checks out the waiting customers. The paramedic starts checking on the man, who has a clearly broken nose. The man slowly regains consciousness, and points to me.)

Thief: “She assaulted me! I’m going to sue!”

(I talk to the police.)

Me: “He grabbed me, but I never hit him. I don’t know how he got hurt!”

(The man, a known criminal, is handcuffed and put in the police car. The officers and my manager go to review the security cameras. About ten minutes later, I get called to come back to the office.)

Manager: “You have got to watch this!”
