Weigh-in, y'all, please:
My dishwasher was on the fritz. It's old. A handyman came by, replaced 2 parts and it's back in action. But, but, but: dude left with the broken part, without asking me if he could take it. Red flag?
I dunno how to feel about it. Feels like stealing, to me. The part he replaced was sizeable. Honestly, I'm surprised he left with it, without saying a word. I didn't anticipate that at all.
Now, in his defense: after he removed the part, it was lying on my kitchen counter for awhile. I casually took a picture of the part, because I do that now, I try to document everything, now, man. He saw me take a picture with my cell. Maybe he assumed I took a picture because I didn't want it anymore? I coulda grabbed it at anytime, it was lying idly on my kitchen counter for the taking. I didn't. Because it's my house. And I fully expected it to remain lying idly on my kitchen counter. It's weird the part's gone.
Should I say something? Should I call his company and call him out?
If you want to be charitable, he may have taken it as part of cleaning up. Maybe it has something in it which requires hazardous disposal, the cost of which was included in the cost of the change. Maybe there were parts of it that could be salvaged and used in other repairs that would not have repaired your unit.
Conversely, it may not have needed repair, and he was running up costs. Maybe it was innocent, and he thought it needed changing but discovered that it was not the cause. Maybe he knew he could sell it for scrap or on ebay. My bet would be that he changed it to see if that were cause, and discovered it was not. There is a lot of appliance technicians who are just parts changers. Whether or not I made a stink would depend on the cost. For me, I would not waste the time for a couple of hundred dollars. I would also factor in his individual behavior and service before making trouble for him.
