In 2016, I unpacked my luggage at a newly constructed New York hotel only to realise that I had forgotten my toothpaste. I called room service, and a chipper voice responded "Someone will bring it right up."
Two minutes later, I opened my door to discover an object resembling a trash can on wheels, equipped with a lid, a large button and a small digital screen. I gingerly pushed the button and the lid opened, revealing a toothpaste tube. The digital display flashed "Thank you." The robotic visitor then turned around and rolled away. Before it disappeared, I snapped a photo, sending it to a friend. He responded, "Nice gimmick."
