The point of being used to playing with Red 5s is if you are willing to call Pon with a Chun as a non-dealer early on in a game with a hand like below.

If you don't want to call tiles, it's ok to ignore it, but if it is early in the game, and the second tile comes out, it is better to call. 
The reason behind this is because calling the tile and winning 3900 points is pretty strong.

Putting your play style of calling and not calling tiles aside, it is important to understand that your opponents may call tiles in situations like this.

But if you are playing without Red 5s, and if your hand is like the one displayed below, it is better not to call Pon.
