Social media like Facebook is the best for me. I tried an experiment. I invited my FB friends to buy my milk tea in the mall where I rented a small space. Then, the next day many fell in line. I was over the moon when they said my FB friends introduced my milk tea to them. They're friends of my friends. They also became my friends. They dropped by at the business center thrice a week and they're growing. I am so thankful to Facebook for the free marketing.
