Gaining Attention

Next is gaining attention. Ho ho, what do you think about attention. Hahaha, it's looks like some activities that you do and your daily life.
Okay, Gaining attention is a way or expression that is spoken so that other people will pay their attention to what we want to.

This is the example of gaining attention :
-Attention, please
-May I have your attention, please?
-Excuse me, look here!
-Listening to me, please
-Waiter?
-I’m sorry, but…
-Wow really?
