An automatic soap dispenser with character
Giulia just wanted to wash her hands in the library restroom, but she ran into a new automatic soap dispenser that operated by its own peculiar rules: it dispensed soap only after she pulled her hand away. She held her palm under the nozzle—silence. She moved closer and waited. But the moment she sharply withdrew her hand, the device spat a glob right into the empty sink. Her second attempt was strategic: hand under the sensor, a brief pause, a quick retreat. This time, the soap landed directly on her sleeve. The machine clearly acknowledged her presence, but refused to cooperate normally. For her third attempt, Giulia placed one hand underneath and the other to the side to catch the drop. When nothing happened, she leaned in close to inspect the LED light. At that exact second, the dispenser triggered and squirted soap right onto her glasses. Groping blindly, she rushed to the touchless tap, discovering it only flowed if she continuously waved her free hand in front of it. From the side, it looked as though she was tearfully bidding an overly dramatic farewell to someone. Drawn by the commotion, the librarian walked in with paper towels and immediately solved the mystery: the sensor housing had been installed backward during morning maintenance. Giulia thoroughly rinsed her glasses, spun the sensor around the right way, and held out her palm once more—the soap dropped neatly into her hand. Finally, she brought her soapy sleeve to the faucet, waved her other hand to trigger the water, and washed her cuff. Leaving the library, she decided to stick to traditional soap bars from then on—at least until her next restroom visit.
