If you go to Las Vegas, make sure to visit the Zappos headquarters. You can schedule your visit online, and the Zappos van will come pick you up. As you walk into the building, you’ll encounter people chatting, smiling and saying hi to you. You’ll also see a big gong in the middle of the large office space. Anyone — including you or any Zappos employee — can go up to the gong at any point and make a big announcement.
