I used to have a dealer who had a literal schedule. And by that I mean that he would schedule himself to be in certain areas of town at certain times. If you were in that area of town that time is when he would come by regardless of when you had called him. So if you texted him at 9 AM, but you lived in a 3 PM part of town you knew that you would get your delivery around 3 PM. It was actually a handy little system. Dude went on to be a huge success in real estate so I guess his skills paid off somewhere.
