That's easy. Every Wednesday morning, this large truck with robotic arms roams the neighborhood, lifts up our trash bins (which we've placed at the curb on the previous evening) and deposits the contents into the back of the truck. Sometimes, it must shake the bin a few times to extract all of the refuse. It then places the bin back down on the ground, near its original position at the curb. Thusly, the garbage has been collected.
Am I hired?
