If you patch a lot of tubes, it's hard to beat the Rema patch roller:

Those of us that ride more plain Jane utilitarian bikes aren't going to bother.
I like late 80's early 90's Rockhoppers. DB CR-MO tubing, but they look ordinary. Why post a pic of that?

I'm not sure that's a real reason; otherwise, shops could offer patching without guarantee at a discount over replacement. But if the cost of patching exceeds that of replacement, there's no incentive to offer patching as an option. Perhaps that will change with hyper-expensive TPU tubes.
Reminds me of an eccentric mechanic I worked with in another shop whom I overheard buttonholing a polite Brit at the Sturmey Archer booth at the New York Bike Show in the early '80's. The S.A. rep kept a straight face as Mike argued earnestly that the company should sell cards of replacement links for indicator rod chains.

As have I. But I suppose I'd note that only about 4-5 of the hundreds of tubes I patch in a given year are from my own bikes - the rest were collected from non-profits which refurbish old bikes, and the patched tubes go back to the non-profits as needed. On Monday, a friend came over and we checked & patched over 40 tubes in a few hours. I only recognized one or two of them as mine.
As for patch reliability - I leave patched tubes inflated for a minimum of 72 hours to test for slow (or fast) leaks and for patch integrity. The attrition rate is about 2-3% - most often slow leaks from a previously-undiscovered hole or a failure elsewhere (typically an old tube). Very few failures of the patch. But when I'm patching in bulk I thoroughly prep each site with a mini-dremel with a sanding drum to get clean black rubber before applying the vulcanizing fluid.
