This is a pretty brilliant Starbucks scam right here. And you'll be disappointed you didn't think of it, because you would've saved a fortune.

A Starbucks employee named Brad Halsey just shared a story with Business Insider, about a nightmare customer at his store who figured out a loophole to get free coffee 365 days a year.

When you get a Starbucks gift card, you can register it with your birthday and you get a free drink that day. This guy bought 365 cards and registered each one for a different birthday, so he gets a free drink every single day.

He goes to the same Starbucks every time, and there's a chance the employees would've let him get away with it if he'd been cool but according to Brad he's not.

Why? He orders an iced quad Venti vanilla white mocha with heavy cream, then he takes the marker and draws arrows on it giving the barista a bunch of extra instructions.

For example, quote, "Two pumps of white mocha here, then add five pumps of vanilla. That should take us to this line here where you're gonna add cold heavy cream up to this ridge. Make sure to add it before the espresso."

Now that this story is out, we'd expect that Starbucks will shut down this loophole.
