I have an old car, a '91 Volvo, and one of it's redeeming factors is the bitching stereo system. Unfortunately, somebody swiped it out of my vehicle and left a big hole in the dash board. Thinking this was going to be an easy replacement I went and bought a new system which was a nearly identical model and thought I could just plug the wires into the new one.
Not so as the thieves took the harness as well and now I was at a loss. I called up Audio Express on Chandler Blvd. near my home and picked the store's manager, Jacob's, brain and he said to come by and he would take a look at it.
Later that day I stopped by the store. Mind you this was 2 weeks before Christmas and I knew Jacob was busy but he took the time to look at my stereo and the hole in my dash board, tell me what part I needed, what OTHER retailer I could order it from and some tips on how to install it properly.
Considering that I didn't actually buy anything at his store and that it was 2 weeks before Christmas I felt Jacob exhibited exceptional devotion to the industry and to customer service.
