ID the SF short story, Part 993774588

This one has bugged me for years, but I can’t be arsed to ask Spider. So, I’ll ask you people.

I read a story back in the 70s that I’m pretty sure had Spider’s pen name of D. B. Wyatt on it. It was a twist on the “Three Wishes” schtick, only this time the genie keeps giving Our Protagonist more wishes and none of them are booby traps. After a middling period Our Hero gets really bored and notices that the genie is having more fun with the wishes than he is. So he confronts the genie, gives up all his remaining wishes and asks to join the genie in messing up people’s lives. The genie then tells him “Welcome to Heaven. You’ve freely given up all you have with no thought of recompense, to go out and do good. Welcome.” Our Hero looks around, smells dope, sees a Chinese buffet and hears Janis riffing with Jimi and smiles. The End.

What in the name of the Seven Buddhas is the title of that story and where can I find it?

Nobody?

Guess I’ll have to bother Spider then.

I’m guessing that you are talking about Spider Robinson, but I’m not finding info that he used the penname D.B. Wyatt?

Sorry, flipped the initials. It’s B. D. Wyatt.

Silversmith Wishes by Robert Sheckley?

I thought I’d read just about everything Spider wrote, and this doesn’t sound familiar (here’s a list of Spider’s works http://www.isfdb.org/cgi-bin/ea.cgi?50).

The Sheckley could be right - the description excerpt here Extrapolation - Google Books sounds right, anyway

That’s it! No wonder I couldn’t find it in any of Spider’s catalog. Now where in the hell did I get the idea Spider wrote it?
eta: That also shows me where I read it - the May 1977 issue of Playboy.

It is found in the collection The Robot Who Looked Like Me. You can read it here.
