This was long before the internet was around so I went to the largest library in town and found a phone book from the town he lived in-this was in Northern California--and looked up about 12-15 residential phone numbers of MD's--they are listed in the white pages ie, Bertram L. Williams, MD and then his residential address and phone number. I called the doctors homes and spoke with their wives. I identified myself as a collection agent representing Dr. Bob Chiropractor and demanded to know why they have not paid their outstanding bill at Dr. Bob's clinic. Of course the ladies denied ever going to Dr. Bob's and of couse I threatened them with small claims court, etc and anything else I could think of. Most of them hung up on me (as would be expected) Now as soon as they got off the phone with me, you know they called their husband and of couse MD's dont have much use for Chiropractors anyway, and so the MD's would be pissed and would immediately call Dr. Laughing Bob Chiro and demand to know why their wife was being harrassed. This completely blindsided Dr. Laughing Bob as he is getting hammered with these calls left and right and he has no idea what is going on. I waited about 24 hours and then I called his office--receptionist answers the phone ( I actually felt bad for her as she was getting the angry calls and had nothing to do with this) and I ask to speak to Dr Bob and I finally persaude her to put me through. Dr. Bob wearily answers the phone and all I said was 'Hey doc, I still have not gotten my payment, have you sent it yet?......long pause and I know he knows that I am responsible and he cant decide whether to cut loose on me or just back off and pay....he finally says, "it will be sent today" and hangs up and I got it about 4 days later
