This coffee shop prank perfectly demonstrates the risk of sharing data online

"We know everything about you, Martin."

Ever wondered how much data a company could gather on you with nothing more than a first name and a Facebook Like?

In the experiment above -- which was shared by fraud prevention company Cifas -- a coffee shop shows exactly that; by getting customers to Like their Facebook page for a free coffee and then asking for their first name, they're able to quickly compile scary amounts of personal data in the time it takes to whip up a cappuccino.

The information -- which is searched for by people in a van across the road and whispered into the ear of the coffee server -- ranges from contact details and past education to current employment and religion.

Big Brother really is watching you.
