Melbourne, Aug 27 In what appears to be the most unique business venture, a guy in Sydney is selling kisses outside the Queen Victoria Building.

Single man Lachlan Christie has been kissing at one dollar for almost two weeks now, and he usually aims to make 5 to 10 dollars per day.

However, the 24-year-old insists it is an effort to break social norms.

"I've sold three kisses in the past 50 minutes. I'm doing it as a social experiment to get a chance to see people's reactions," The Australian quoted him as saying.

But he still hasn't met enough women who are ready to receive kisses on the lips.

He added: "I want some brave girls to come up. A lot of people want to give me money but don't want a kiss."

Lachlan mentions that he is not trying to find a girlfriend.

He said: "It's mainly for the reaction ... to break down boundaries and challenge social norms," he said. Once I get more well known, hopefully business will boom. It's great toeing the line of whether people think you're serious or not."

Sydney's Free Hugs Man, who is known by pseudonym Juan Mann, apparently inspires Lachlan.

The "Free Hugs" movement started at Pitt St Mall in 2004, which later became a rage worldwide. (ANI)
