When you know someone who owns a certain business, you usually try to be supportive. You may buy things from their business or you may try to help advertise the products they sell. This is something that you would appreciate if you were the person who owned the business and so you do it to help your friends. I know someone who owns a company that designs clothing and for this reason, whenever I have the opportunity, I will always talk about branded southern sisters shirts. My friend who owns the company has mentioned several times that this has helped her business a lot.
