Some preparers don't realize that when they send clients away, it is costing them money.  The client isn't always right, but is always the client.  I have some PIA clients that I would like to send away, but then I remember the referrals they have sent me, who have been much easier to work with and for many years have been putting food on the table.  Sometimes even wine and amaretto for dessert.  

There are no young preparers around here, except maybe for that kid who is in way too deep with the inherited small-town practice, but a word of advice occasionally deserves to be repeated. Don't be a grouch.  Very few things in life are worth worrying about, and the occasional inconsiderate client is not one of them.  100 years from now it won't make any difference.
