An alert cashier at a Kroger supermarket in Sylvania, Ohio was able to talk a grandmother out of being scammed of at least $2,000.

When Shelly Yost saw the elderly woman attempting to buy $2,000 worth of iTunes gift cards, she questioned the need for such a large purchase of the cards. The woman explained that she received a phone call from a someone whom she was convinced was her granddaughter, who said she was in jail and needed help - and, apparently for dramatic effect, also had a broken nose. She believed these gift cards were somehow a form of bail that needed to be exchanged to let the granddaughter out.

Yost knew this story didn't add up.

'I wouldn't sell them to her...and, I was afraid she was going to go somewhere else to buy them,' Yost said while joining the Keeler in the Morning Show on WIBX Wednesday. She told the customer of her belief that this was a scam, and called the police for her to confirm that her granddaughter was, in fact, not in jail.

The woman fell for what seemed like such an off-the-wall premise because the imposter was 'very convincing' and 'knew things' only the woman's granddaughter would know.

'I think [she] was just really scared and wasn't thinking about it. She was just worried about her granddaughter,' Yost said.

Those 'things' that 'only' the granddaughter would know are sometimes taken for granted and can be absorbed by looking at the average Facebook page or social media account: names of relatives, locations and guests at family functions, and plenty of other 'personal' information.
