@bengy, Pre-plannedaspect should be included when we go for outings and to restaurants because it's about the Distribution of Expenses. But everytime it's not the case sometimes it's about the Treat too.

But when it comes to Distribution Of Expenses people should be clear because many times these things turn out so serious or so funny and embarrassing.

Whenever i went out with my friends we preplanned about the expenses most of the times.

Have a great time ahead and stay blessed.
