Dr. Lech insists that any new clients he takes on in therapy agree to first attend a weekend retreat that involves his proprietary 28-step program of Sensual Touching, Erotic Reawakening, and Intimate Exploration. The cost of the $2,500 weekend must be paid in full up front, and in return Dr. Lech commits to participating in all 28 steps with each client. His policy is that this is a required first step for those seeking treatment at his smoking-cessation clinic. When would Dr. Lech's policies be allowed by any governing board of psychology?
a)  never
b)  if he required only a $500 deposit before proceeding
c)  if clients could be reimbursed by their insurance companies
d)  if the 28-step program could be paid in 28 installments
