Funny, I get the exact opposite in my two local radio shacks.
There's always only one or two employees, and they are always both busy signing up somebody for cellular telephone service (which takes like a fricking HOUR during which time they completely ignore all the other customers who just wanna buy a 49 cent capacitor and get the hell out of there).
The cellular telephone stuff carries some pretty good kickbacks and commisions to the store and the employee, so that's where they've been making their money these days. Same with the little-dish satellite services they sell.
