The gameshow participant made the announcement as she was interviewed by host Bradley Walsh ahead of answering questions for cash.

Sandy, 54, from Nottinghamshire, explained to viewers that her main job was as a teacher, but added: ” I do teaching alongside the job I do now as a mystery shopper.”
This statement was followed by an influx of astounded Twitter posts, as a straight-faced Bradley continued his questioning.
One Chase fan wrote: “Mystery shopper on #TheChase. That’s your cover blown, love.”


“A mystery shopper going on TV is a bit like James Bond telling everybody he’s a spy. #TheChase,” added another.
One joked: ““I’m Sandy, I’m 54; and I’m a mystery shopper from Nottinghamshire.” Not anymore you’re not, love!”
Continuing to show concern that unsuspecting Sandy may have just lost her job in front of millions, a viewer added: “Well she isn’t a mystery customer anymore!”
Following her revelation, Sandy added: “Basically I make loads of phonecalls to Government departments, banks and offices and see if they’re following regulations and then I write a report and send it off.”
She then went on to face The Governess, Anne Hegerty, and managed to bag £5,000 for her smiling team.
