Offer a free one off reshoot then tell them similar bookings will be on a $/£/€ per hour basis with a 30 min overshoot thrown in for goodwill (actually to keep their business as the client is always right), and anything over is charged at the hourly rate. If the company are decent they'll think you've made a special allowance for this job and rebook you. If they're ***holes to work for then you're better off without them.
