You get a table to hang out at.

Some one brings you a menu.

So you order your burger and fries and cola flavored beverage...

After the wait-person leaves,you don't sit and brood about whether or not they will have enough fries...

You don't ruminate over whether or not the soda will be cold...

You don't worry that they might run out of buns before they get your burger up!

Confidently,you wait believing the meal will be delivered to you as you ordered in a reasonable ammount of time.
