Vietnamese singing for their supper

In Vietnam, where karaoke is not only recreational but also business etiquette, failing to show your talent can cost you dearly.

Tien Phong newspaper reported that state oil monopoly Petrovietnam's financial arm PVFC ordered 21 officials to make "self-criticism" reports for not singing karaoke at a contract-signing ceremony near Hanoi.

At least eight department heads were facing suspension.
