In 2016, I unpacked my luggage at a newly constructed New York hotel only to realize that I(forget) my toothpaste. I called room service, and an(energy) voice responded, "Someone will bring it right up." Two minutes later, I opened my door only to discover an object resembling a trash can on wheels,(equip) with a lid, a large button and a small digital screen. I cautiously 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,later responded, "Wow, so cool!"
