Consistancy is key to any Service Business Growing Larger

Have you ever had the experience of having 2 of your customers compare their bill?  You had Bob go to one customer and the next day, Tom went to the customer's house across the street the same job?  Then Mrs. Smith and Mrs. Jones got together the next day and compared their bills only to find they payed different amounts of the same service from your company?
