More than a year ago, New York City passed a law banning cell phone use in theatres. Many thought the ban was unenforceable. “Broadway, Off-Broadway, and Off-Off-Broadway house managers asking audience members to turn off their cell phones before a performance begins is now a completely common practice. But has there been 100% compliance? (Anyone who attends the theatre today might suspect otherwise.) Has anyone paid the fine? Has anyone been physically removed for defying the law?”
