Automatic flush toilets. Either they flush too often and freak out the little children in the stall beside yours, or they don’t flush at all and you spend your time waving your hand in front of what looks like the sensor, until you run out of patience and leave the stall unflushed.
Automatic sinks. They will work fine when you begin the process, but when you wish to rinse your hands, the sensor will not work and you will spend too much time waving your hand under the faucet, until you run out of patience and leave with your hands unrinsed.
Automatic paper towel dispensers. These will work fine for the person ahead of you, but the sensor will not work for you, so you will spend too much time waving your hands in front of the little dot labeled as “Sensor”, until you run out of patience and leave the restroom with your hands undried and unrinsed.
