Always tip the bouncer – or else.

Such was the takeaway from an encounter in Phnom Penh’s Tuol Kork district on Tuesday.

Police said a young man – who was admittedly three sheets to the wind – was exiting the club when the security guards asked him for some money.

When he failed to cough it up, however, they pounced, beating him badly and leaving him seriously injured.

Police are now on the lookout for the vindictive doormen.
