Good for you if you live in a culture without strong T-V distinction. Not using the correct form of address will make you need perceived as impolite in the best case or highly disrespectful and confrontational in the worst case, and you will land on their sh*t list. This can be dangerous if you have to interact with police!

PS: even in English, you're probably not using as many F-bombs and S-bombs when you talk to powerful people.
