Info from Licensor: "These customers consumed a yogurt inside the market and threw the packet in the trash. After that, they paid. When they left the market the security asked for the receipt, and she asked him to go away. The security guard said he would not let them go because they hadn't paid for the yogurt they drank inside. They were drunk and started cursing at the security. One of them spat at him, and that was the moment he retaliated."
