Why should men/Guys always pay for Ladies/Gals?

So its a female saying cuz men n women are really not equal. Why its always like that? and then later on saying that I am neutral for both.

**men like to show-off that they really have the power.

**Its not power but being charming and smart makes it happen. I haven't paid it like this because never got time for this. :D

I know now you will say I just joked.. :D
