Do-it-yourself repair shop

In Vancouver, British Columbia, there is a motorcycle repair shop that lets you use their tools and someone shows you how to fix your bike yourself.  Here is a video about the business, which is called Motomethod:

The Motomethod Story from Zenga Bros on Vimeo.

The video shows the two owners enthusiastic about their vocation, including their zeal to love and serve their customers.

Would you say the do-it-yourself impulse is an example of vocation (cultivating your talents)  or the repudiation of vocation (not letting yourself be served by someone else)?

Can you think of other businesses built on this model?
