I was selling a house one time and the people failed to show at the appointment.hahah, it was SO weird. We've run over on time /owners thought appt ended earlier than it did once or twice before and they've always been so pleasant about it. We always left right away and they would be like "oh, sorry," and then ask if we had any questions. Even if the list agent didn't tell them about the time change, we weren't over on time and were actually heading to the door to leave.
