Customers at two faulty ATM's were given double their money when a technical glitch hit the machines this week.
According to the Daily Express, more than £50,000 was erroneously delivered to delighted customers at the cashpoints in Manchester and Wales.
Queues quickly formed at the Nationwide ATMs as word spread about the fault until one customer phoned the building society to report the problem.
The bank said the notes were loaded in the wrong way, adding that it was "disappointing" that it took six hours for someone to report the fault.
Would you have reported it immediately or would you have enjoyed a windfall?
