On the heels of a hilarious Super Bowl campaign ad promising to shed its stuck-in-the-’80s image, RadioShack announced this week that it’s closing 1,100 stores nationwide. The company has not yet released a list of the doomed stores, and staffers at the Cabin John and Rockville Pike locations say they haven’t heard any news so far. But a RadioShack employee at Westfield Montgomery Mall was quite confident that his store won’t be affected. “No way,” he said. “We’re the number one store in the district.”
