A Spanish bank gave 270 of its staff a massive surprise when it mixed up euros with pesetas on pay day.
The workers from the Madrid computer firm were paid in euros - the same number as they usually got in their far less valuable national currency.
Computer firm Arcitel Iberica noticed the mistake after a few hours and the unexpected bonus was quickly withdrawn.
"Luckily our workers realised straight away that it was a mistake," explained the firm's owner Jose Fernendez.
Workers who are usually paid 200,000 pesetas a month (about £770) suddenly got 200,000 euros (about £127,500).
