Create a 3D model of a surreal humanoid waiter with a sleek, formal black and white uniform, holding a silver tray. Instead of a human head, the figure has an old-fashioned street lamp for a head — complete with a glowing, slightly flickering bulb inside. The lamp-head is metallic, worn, and slightly rusted, with subtle engravings or numbering. The light from the lamp softly illuminates part of the waiter's shoulders and chest. His posture is elegant and professional, but the unnatural fusion of man and lamp gives the character a mysterious and unsettling atmosphere. The background should be neutral or dark to enhance the glow of the lamp.
