While he was putting his personal belongings in the free locker provided by the library, a boy about the age of 10 came by.
The boy was holding two plastic bags from a bakery (of course there's bread inside). He put them into the locker just below the man's one, closed it, used his hands to cover the keypad lock and waited. The boy was apparently waiting for the man to walk off before keying in his password. He was afraid that the man will see what his password was.
The man was amused by the boy's action. As he walked away, he turned to see what the boy did.
The boy entered 1 to 9 in its order as his password while one of his hand was still covering the keypad to make sure no one can sees it (even though there's no one else). He probably thought that the more number he used for the password, the safer it will be.
What caused a 10 year old boy to behave like this?
What's the implication for your business?
