Anywhere there is space can be a toilet, this is probably what two female Chinese passengers on a Shenzhen Airlines flight thought last weekend.

According to the news siteNetEase NewsPassengers on flight ZH9709 from Nanjing to Guangzhou on August 16 complained that the two women above let a boy, the son of one of them, "defecate" behind the cockpit.

Witnesses said the incident happened despite the fact that both toilets on the plane were empty at the time.

A flight attendant reportedly witnessed the child “misbehaving” before take-off, with the mother and her relatives happily assisting the child as if they were in a toilet cubicle.

When asked why she did not let the child use the toilet, the mother replied calmly: “Your toilet is too small for the three of us to go in. It is much more spacious outside.”

This is not the first case of its kind. Last summer, a Chinese family made headlines when they allowed their child to relieve himself in the aisle of a Delta Airlines flight from Beijing to the United States.

In 2013, a mainland mother was photographed letting her son poop on the floor at a Taiwanese airport, less than 25 meters from a toilet, according to Shanghaiist.
