One time i saw a video like this on TV that was hilarious as fuck. A guy walks in a store like that at night time and there's like 2 customers in the store. The guy pulls out his gun and threatens the cashier. The cashier acts like he doesn't know wtf the robber's talking about. One customer was standing next to the robber and at first he's continuing shopping and then he asks the cashier where the restroom is. The cashier tells him where it's at and the guy goes to the restroom.They both neglict the robber and so he is stunned and can't believe what's happening, so he just looks around like: are these ppl crazy. He points the gun at the customer that wants to go to the restroom but the customer doesn't respond and continues his path to the restroom. Then the robber continues to threaten to cashier and asks for money, but the cashier responds with a vage answer and just stands behind the counter doing nothing. The customer comes back and i think he just left the store or started talking to the cashier again and then the robber just took off.
Now that's funny !!
