Scammed at the Mall

These two causasion males pulled up to my car while I was listening to my radio in the car. They were driving a blueish green Lincoln Navigator, said it was their bosses. They told me about a miss-order and they had extra speakers. They said that this has happened before and their boss would just get the speakers. Then they asked me what I was willing to pay for them, they just wanted some party cash. I was shocked. I said that I was in college and only had $50 in my checking account. In reality I have close to $3000. Good thing I didm't tell them that. I told them they had to come with me to my bank to clear out my checking account. I made a big deal out of it. Maybe my bank has some security cameras on the parking lot. I'll have to check that out. Everybody is right this has to stop now.
