Clinic staff were left stunned after witnessing a couple openly showering with a hose outside their office.

The bizarre incident happened outside Kritchamon Clinic in Bangkok, Thailand, on July 2.

Footage shows the husband holding up two coloured umbrellas to shield his wife as she stood beside the building, using a water hose to wash herself in public.

The woman was seen crouching by the wall, calmly removing her shorts, and appearing to wash her backside with the running water.

Before casually walking away, she reportedly said: 'Please let me take a poop. I really can't take it anymore.'

Inside the clinic, confused staff were wondering why the building had no running water.

The doctor said: 'The water at the clinic was out all day, causing serious inconvenience. We eventually had to call the waterworks.'

Later, while reviewing CCTV footage, staff spotted the man approaching a valve just outside the clinic. He was seen deliberately turning it on and then switching it off again once the woman finished.

It is believed the couple's unauthorised use of the valve disrupted the clinic's water supply for several hours.

The physician added: 'She clearly saw the camera but didn't seem the least bit bothered.'

The clinic did not report the incident to the police, citing time constraints and limited resources during operating hours.

A previous break-in had also been reported without resolution.
