If it takes 5 minutes to do the work on your wheels, why exactly aren't you doing it?
Shop rate around here is $80/hour.
Right, wrong or indifferent, when I see those rates I always think to myself, "are you gonna fix my car / bike or defend me in a capital murder case ?"
I always feel a little bit better when they charge $8 / ft for brake cable housing.....oh wait...never mind.
