Collecting the money from customers is often a challenge. You need to be friendly with your customers so they continue to order, but you also need to be firm so that you get paid in a timely manner.... Its a hard balance.

I know a small business owner who has a mythical staff member called Tony. Tony collects the money by being a pitbul...this is very successful as it allows the company owner to do what he does best and he leaves the mythical Tony to chase the money.
