In Bangkok, it is a familiar site to see someone feeding the elephants bits of fruit. People even pay the elephants handlers to be able to do this.
The act is very dangerous and many people have been injured as a result. Elephants and property have also been hurt as a result of these improper feedings.
To protect the people, the elephants and the property, the authorities have decided to place a fine on people when caught feeding the elephants.
So if you visit Bangkok, do not feed the elephants.
