The incidence happened when a cashier at Jimmy Johns restaurant in Kansas was having a usual working day. The customer came and had a brief talk but after a while he pulled out his gun and asked for cash. Anybody would have panicked in this kind of situation but this cashier was so calm and handled the situation without any stress. The cashier even calmly removed his gloves before handing over the money. The suspect is in police custody.
Have look at the video.
