To make a maintenance appointment, does a client need to wait at home for a 6-hour appointment window, have the technician show up late, and track mud through her freshly-cleaned carpet, no wonder she called to argue about the bill.
My husband and I are spending 4 hours round trip in the car today with Mom, plus the 1 hour waiting and the appointment time, practicing what we preach.
Because most of their patients live fairly close by, it's generally not a problem to do a home exam and get back to the office in the hour that is scheduled for an appointment.
