Well like I said, he'll just revert back to the original name, "<Hometown> Electronics" (where <Hometown> is the name of my hometown). He answers the phone as "<Hometown> Electronics RadioShack" as it is, so he could just drop the RS branding.
I say it's sad because it's a strategic location for a RadioShack; the one in the nearest town over dropped the franchise long ago and the owner merged his business with a local hardware store. So for about 30 miles all around, it's the only RadioShack. I have a feeling though, his regular clientele will keep him afloat, and he's smart enough to know how to keep new people coming in.
