The dispute has fed a wider German debate over immigration and national identity, especially after the large influx of migrants over the past decade. Online, reactions split sharply between people who said the rule was absurd and others who argued newcomers should learn German rather than demand translated signs. A lifeguard named Johann, who works at a municipal pool in the migrant-heavy Berlin district of Wedding, said signs could be multilingual and announcements could be recorded in several languages, but he argued that many visitors still ignore warnings and that enforcement is difficult. He added that the underlying problem is that lifeguards are expected to be polite and resolve everything peacefully, which does not always work.
