I'm surprised at comments about the cost of plumber service calls given SF HNers are often programmers commanding 6 figure salaries themselves. Something plumbing and programming have in common is that both are high-demand specializations that most people are not willing/interested in spending their time with. It should be no surprise that these specialists' time isn't cheap.
