Again, my opinion.
Don't be so sensitive. I said to each his own. In other words, do what you want, but it is not how I would do things because I feel that is a sorry way of doing things. You clearly do not. That's your right. No need to get bent out of shape.
While I do agree with you, you did come across a little condescending. I agree with you simply because you never know where that next referral is going to come from nor do you know what that client might need in the future. In this case, it's a simple med supp. No reason why there should be any service calls for the most part.
I can't tell you how many times I've helped someone without getting paid and it came back to me in different ways. Sure, there have been a few that never referred or I never got anything out of it...but I didn't lose either.
