Never again.
Only use? Well, a very good use if the printer can't deal with anything but an abstract space and you want to anticipate what the print may look like.
However, I've never been able to understand why, other than because of ignorance, a printer who can make a conversion to a device profile from sRGB can't do the same from ProPhoto or any other space that contains all the colour information that you might want to print.
OTOH if they really don't know anything about colour management, then giving them the file encoded for their printer and requesting it be printed without any further colour correction would be a good solution, don't you think? Although I concede that it's most likely that a printer who didn't know anything about colour management is almost certainly not going to know how to print without colour correction either.
This, incidentally, is why I do all my own printing.
My good reason would be that I want to preserve all the colours I have. Agreed, if there no highly saturated colours at all in the image it hardly matters what colour space you use. But, on that basis, it seems that sRGB is the exception, rather than the rule. ProPhoto will cope with any colours an image may have.
