A woman urinated in an electrical shop in Xi'an, China, after she failed to get a refund for a soya milk maker, reported Guang Ming Daily.
The woman had demanded a refund for the appliance she bought a week ago, as well as 200 yuan (S$44) in compensation.
When the shop operator refused, she knelt and urinated in front of other customers in the store.
Shocked, the operator called the police for help, but even they failed to get the woman to leave the store.
She agreed to leave only after the operator paid her 50 yuan.
The woman has since been criticised by netizens, after customers uploaded photos of the incident on the Internet.
