To demonstrate with a example where I attempted to charge something I thought reasonable. I used to do a lot of puppy farmers bitch csections in the middle of the night. We had no duty nurse so had to phone around the nurses and it was the same thin, overworked, anxious woman in her late 60s that answered and came down at 2am to do the anaesthetic and revive the puppies without fail, every time for zero £. I put a £15 OOH nurse sur charge on once. Puppy farmer complained, I got a bollocking, puppy farmer got £15 refund end of story.Charging £90 for a pill that the client has collected is just bad business and bad public relations, especially as the client wasn't fore warned. Sorry, but if my vet did that to me he would get an ear full!
