Now this is how you take advantage of a discount! The Montana Club in Missoula, Montana has a deal where if you eat there on your birthday, you get your age as a percent-off discount. So if you're turning 50, you'd get 50% off.

That discount has worked out great for Helen Self, who just celebrated her 109th birthday. When she went to the restaurant, she didn't just get her meal free, the Montana Club paid her 9% of the cost back in cash.

Helen's been going there for her birthday every year since she turned 100. The owner says that even though she found a hell of a loophole on the discount, he's happy to take care of her every year.
