Four days after signatures, he gave me a debit card number. Returns were submitted and accepted, and his copies mailed to him (first class, not Priority). I'm done with him, and it was technically only a day later than we are "supposed" to wait. But it also took him three different promised times to call me to pay before he came through.
At some point in the next few weeks I'll make sure he knows that was a last-time courtesy for his mom's sake, and that I have no unaffiliated individual clients that I work with under the age of 80. (That last is true; sold off the bulk of my practice some years ago. Kept the elderlies 'cuz change is too hard for them plus - let's face it - they're not long-term clients. Also kept family and a few friends and charity cases that I do for a song. Anyone who wanders in new gets referred out to the guys who bought me out. He is not his mom, and he's under 80, so he's also history. Better ask the guys if they want him, or not...)
