I'm curious to know from repairers and customers their opinions on the
following:

Tech "A" is well versed in repairing a "duo-amp" reproducing piano.
He has worked on many of them and can diagnose and repair a problem
very quickly.  He charges $75 per hour for his services.

Tech "B" is good, but does not have a lot of experience with a
"duo-amp".  When working on the piano, he is much slower than the other
tech.  He needs to have his reference materials at hand and look things
up as he goes, but he eventually does get the job done.  He charges the
same as the other technician: $75 per hour.

Both can get the job done in a satisfactory manner.  Tech "A" comes
out to fix a problem and it takes 1 hour; Tech "B" comes out and takes
2 hours.  Should the price charged the customer vary?  If "A" gets it
working for $75 but "B" charges $150 (twice the time), is one charging
too much?  Is one charging to little?

In some businesses (such as auto repair), they can use a book that
states "replace radiator cap = 3.6 hours", and the shop simply
multiplies the shop rate by the number of hours it "should" take.
This easily takes care of any disparity between workers as to how long
a job takes to get done.  There is obviously not such a thing in the
piano repair business (as far as I know).

I'm just curious as to what responses I might get by posing this
question.
