I've been to RadioShacks all over the country. Every single one is exactly the same.
There are always two employees there: one working the register, and another whose job appears to involve randomly going in & out of the back room for no reason.
There are always at least 3 people in line. Inevitably, at least one of these people will want to buy a cell phone despite having no clue what one IS. Either that they'll ask for a battery for their cordless phone. They won't know the model or even the brand name, and will get all huffy and say "Well I BOUGHT it here 4 or 5 years ago, can't you LOOK IT UP?!?"
The RadioShack in my local mall stopped carrying electronics parts a couple months ago. As far as I'm concerned there's no other reason whatsoever for them to exist, since you can get a better brand of pretty much anything they carry for about 40% less at any other store. RS sucks.
