How do most German men carry their laptop and documents to work? For example, in China, adult men do not usually carry a backpack to work, but instead use a laptop bag or a document briefcase. Backpacks are perceived as "juvenile" and "only for students". In South Korea, however, backpacks are quite fashionable. And even adult men wearing suits will still carry a backpack to work. What is the norm in Germany? What about in the IT industry? Especially at a company that has no dress code? Danke!
