Don't lost your temper. be patient...

If someone is rude to you:

1) Take a deep breath and respond calmly, yet firmly.

There is no need for you to become rude in response. Maintain composure and understand that any kind of behavior meant to "get at you" is meant to unbalance you. Breathe a few times, and resist the urge to lash out.

2) Call attention to the situation, error, or issue by speaking directly with the person.

Many people get more angry or out-of-control if they feel like they are being attacked. If you need to instru
thank you for that but if the situations go out of my control what do i do?
We should be polite to everyone but if someone speaks rude to you in public place then also you should speak campy to him/her.
