I have no idea what the technician did that he thinks could have justified him being at my house for an hour. He was supposed to bring a dimmer switch with him and apparently did not do so, so it appears he drove around for at least a half hour looking for a hardware store. He didn't install the track lighting, so putting in the dimmer switch wasn't necessary if he wasn't going to install the lighting. He did point out that I needed 4' more of track than I had, but he could have installed the lighting i did have and I could have had a functioning light that was a little smaller than I planned until I bought the additional 4' of track. I am enormously frustrated with this total waste of time by your technician.
