The matter of financial arrangements between patient and druggists are best left to the parties most concerned. It is an unfortunate practice for the prescriber to take to the drug-store the prescriptions for parties unknown to the pharmacist and recommend that they be filled and charged. A like practice is to mark the prescription, when not taken in person, 0. K. or a/c O. K. There are sometimes exceptional circumstances that would justify such action, but such is rarely the case. A refusal to recognize such recommendation is frequently embarrassing to the druggist, physician, and patient, and the prescriber should only make such suggestion when he intends to pay the account if the patient should not do so. The fact that the patient lives in a nice home and pays the bills of the physician, whom he likes and needs, is not always a certain indication that he will pay the pharmacist, whom he does not know or care about. The prescriber may feel that in recommending that the pharmacist extend credit for one little prescription the matter is small anyway, but the end result may be the opening up of an extensive account and considerable loss to the druggist. It is certain that this class of interference is usually unnecessary, undesired, and unappreciated.
