Vandalism or any form of intentional damage to public facilities is illegal and unethical.
Air hand dryers are essential amenities in public spaces, and tampering with them can disrupt the functionality of public facilities and cause inconvenience to others. If you encounter an issue with an air hand dryer or any other public facility, the responsible and ethical approach is to report the problem to the appropriate authorities or the establishment's management, so they can address it and ensure that it functions correctly for everyone's use.
Remember, being a responsible member of society means respecting public property and ensuring that everyone can benefit from shared resources without causing harm or inconvenience to others.
