@woozle Exactly. My daughter used to manage two Radio Shack stores at once, and very successfully. She's been a ham radio operator since she was 14. One key to her success was continuing to cater to the electronics geeks despite the store turning into a cellphone store. They'd come from miles around because they knew she had what the needed. And then they went out of business.
Radio Shack management REALLY screwed up. When the modern electronic hobbyist boom took off, they were unprepared because the store was full of cellphones instead of Raspberry Pis, Arduinos, perf board, and parts.
