If you attack you will get nothing and possibly give the vet a good reason not to deal with herps at all. If you help him/her to learn you may get a partial/full refund and help some one grow and learn.
Good Luck!
And how would it be a bad thing if he stopped dealing with herps? And as far as learning, I would think that he probably should have learned in vet school not to treat animals that he isn't qualified to work on!
