I came in for a blinker bulb and the gentleman there installed it for me. After learning that the new bulb didn't fix the problem, he checked the fuses and after further investigation, found the problem. He made a simple fix to the part, installed the new bulb, and I was on my way. He didn't have to figure out what the problem was; he could have sold me the bulb and sent me on my way, but he didn't. For that, I am grateful.
