For anyone with a Starbucks card, the firm gives you a free drink of choice on your birthday - something one customer was all too keen to exploit.

The clever trick involves taking out hundreds of reward cards in your name and registering your birthday for every day of the year, with a different day on each card.

Details of the plot were shared online by the barista who uncovered it, in a comment thread about the worst kinds of restaurant customers.

He wrote: "There is a man who comes to my Starbucks every single day and orders the most horrible drink in an infuriating way.

"He purchased 365 Starbucks cards and registered every one of them online with a different birthday so that he gets a 'free birthday drink' EVERY DAY OF THE YEAR."

However, this seems to be in breach of the Starbucks card's terms and conditions, which state that you cannot take out more than one card in your own name.

It's worth bearing in mind that you might not be so lucky if you try to make a mocha-ry of the coffee chain's generosity.
