I saw on your agreement that I will be charged mileage fees
If the subject exits the 30 mile radius, we will first call you to get approval for continuing outside the area. If you agree to that, we will bill you at the rate of $0.45 per mile. We cannot tell you what the total will be in advance, since we will not know where the subject will be going. But, know that you can cancel the surveillance at any time.
