Youu pay your plumber if they show up, not only if they successfully fix your toilet.
I don’t see the connection between “should you pay your plumber even if they don’t actually fix your toilet” and “should you pay your plumber twice as much if they fix your toilet twice as well”; the latter seems like a nonsensical question, and unrelated to the former.
