A screen grab from the YouTube video showing Singaporean traffic wardens' motorbikes parked on double lines.

Two Singapore traffic wardens got a taste of their own medicine
when they were photographed having breakfast - with their
motorbikes parked illegally nearby - after "busting" a rush hour
motorist.

The unidentified motorist used his camera phone to film the pair
after being annoyed when he spotted them taking pictures of his car
in a bus lane, the Straits Times reported on Saturday.

He posted the video clip on
the internet's popular video-sharing website, YouTube, the paper
said.

In the two-minute video, the man is heard asking the wardens why
their own vehicles were illegally parked - to which one of the
wardens replies they were just "doing our job" before brushing him
off.

The newspaper said the the wardens were now in trouble with
their employers, a local public transport company.

While not empowered to issue fines, the wardens can submit
photographs of errant motorists to police for further action.

The video has already been viewed thousands of times on YouTube,
with normally staid Singaporeans gleefully praising the citizen
ombudsman.
