Why so many double standards?

I work for an internal medical doctor, have been with him for 5 yrs. He is from Syria. For the past 5 yrs I have stamped his signature on many forms, prescriptions and have called in many scripts for him. Over theXmas holidays he was out of town and left a stack of signed scripts for patients who had to have their narcotics and threw such a fit because they couldn't wait until their next appt, after the holidays. We wrote the scripts and everything was fine. Sometimes this doc will call in peoples narcs (pain meds, Xanax, sleeping meds, Klonopin) and other times he stands firm that legally he has to see the patients and can't write the meds. On some patients he claims he has to see them every two weeks in order for them to get their meds. He has been treating myself and my husband for the years I worked for him. He knows what we both take and what we both refuse to take. My hubby started on Ambien and Xanax, as prescribed by him in Oct 2009. In Jan. 2010, the doc seen my hubby and told him since he didn't have insurance he would do what he could to help us until he got back to work, He told me that I could call in his scripts when needed. His last script for Xanax was in Dec 2009, so on Thursday, I faxed in my hubby's Ambien and Xanax with his stamped signature. I was planning on telling him about it later that evening but a the pharmacy tech called and made a huge deal out of it, thinking something funny was going on. The doc flipped his lid. He called me into his office and told me he could lose his license, and he wasn't sure what the pharmacy was going to do about this situation. He kept on and on. I kept telling him I was sorry and that I was going to tell him but we were so busy. He wouldn't shut up about it so finally I said I would just quit. Still he kept on and on. So I said I would never write or call in another script and give him back his stamp. Still he kept on and on telling me how he trusted me and how he didn't know what was going to happen. I again repeatedly apologized. He never spoke another word to me the rest of the day and totally ignored me like I was even present on Friday. I know I should have asked him first before faxing the scripts but I honestly didn't think he would mind. He runs his office on so many double standards me and the other employees never know which rules to follow. Plus this doc will charge people an office visit if they call and ask for a refill on their scripts or for something to be called in for a sinus infection or whatever. He doesn't even see them. This man is so greedy and unappreciative of his staff.
