Passenger's forgotten bag causes flight turnaround due to selfishness

A passenger on a flight from Chiang Mai to Bangkok demanded the plane turn back to the gate after realizing he had left his bag at the airport lounge. Despite attempts to reason with him, the irate traveler insisted on returning to retrieve his bag, causing a disruption. Security escorted the passenger and his companions off the plane upon its return to the gate. The flight eventually took off and landed safely in Bangkok. In a similar incident, a United Airlines flight had to be diverted to Chicago after a passenger became upset over not getting his preferred meal choice.
