Word of mouth references in offline business? | NewProxyLists

When you have an offline business, it can be advantageous to have references by word of mouth. And this way you can get consistent leads. I'm also trying to base my business on local customers. Since most concerts are online, it can be harder for me to get offline referrals. I therefore hope that with the referrals offline, I will be able to fill some of my sabbatical days with offline business.

So how do word of mouth references work in offline business?
