Public transport systems around the world require people to "tap off" their travel cards when exiting a bus or train, and forgetting to do so is a big (and expensive) headache.

But public transport investigators in Australia's Sydney were stunned to find that one of 22 passengers escaping a bus fire last September, went back to the flaming bus try and "tap off," according to Fairfax Media.

Guess the unnamed passenger really didn't want to pay that annoying A$4.50 (US$3.45) day rate, which is arguably the bane of all of Sydney's existence.

CCTV footage discovered the passenger making their way to the bus, risking their life to ensure they wouldn't be slammed with the higher charge.

And honestly, who could blame them? It's likely easier than trying to get your money back from the Opal Card ticketing people, according to the internet.

Luckily, no one was badly hurt, but two passengers and the driver were taken to hospital for smoke inhalation.

It's uncertain how many were hurt by the default fare, however.
