Tame butcher?

I get the majority of meat from the butchers, which is easy but quite expensive for the cats and a pain in the butt but cheap for the dogs. A lot of butchers have caught on and are making the most of BARF/RAW feeders by making their own raw dog food but I want actual bones and actual meat so I had to shop around for a bit to find a good butchers, I now get all the meaty bones for the dogs free. I was paying pennies for carcasses and bones from a wholesale butchers but they were very unreliable so I only go to them now and again to stock up on chicken carcasses for the dogs. Everything I feed I can get from the butchers but I must admit to taking advantage of the offers at Tesco as well.
