Hmmmmm, odd. I got a letter last year when my very first patient dropped me. It just said that I will no longer be providing care for him. It was funny because this patient talked me into this growing thing and then told me he would match me on equipment costs to get started and then after I spent three grand on gear, he stopped answering my calls and never spoke to him again. I'm guessing he just wanted free herb and didnt have the balls to tell me he couldn't afford to match me on the gear costs afterall. To be honest, I'm happy it turned out this way anyway because I own ALL of my shit. NOBODY else helped me get where I am today so I owe thanks to myself and I don't owe a stake of my resources to anybody. The lesson I learned was to be very careful about screening people before agreeing to something like this.
Sorry for the long tangential rambling. The point is, yes, the former caregiver SHOULD get something in the mail stating he has been dropped.
