Directions for the toilet
It’s reasonable to guess that most people are familiar with how to use a toilet. However, there are actually toilets with numerous flushing mechanisms (to put it another way) for varied flushing requirements. This is one of those toilets, and someone had the bright idea to label the buttons according to what they did.
Most people are familiar with the term “number two.” As a result, it is clear which button to push for anybody who needs to do so in this toilet. Thank you very much for that essential information.
