I agree--it's laziness and an "I don't care" attitude.

We also get calls for copies of returns.  I do remind them that we give them a copy every year but they are too lazy to look for it.  So we have to take time out of our day (unchargeable) and get it for them. Quite annoying.

We've started a list of clients we are firing.  Some are just not worth the time or hassle anymore.
