Let me see if I have this straight:

The OP handed an LBS he usually doesn't do business with a used rim and spokes and a replacement PT hub purchased elsewhere for a rebuild on Tuesday with the expectation that the job would be done by Friday. On Monday the job isn't completed and so he's written them off as terrible and lacking customer service. When, he's admitted to not spending any more at LBS's than is absolutely neccessary (tubes, etc.).
