Additional Restaurant Analogy for Demos - "I'm Full..."

This one is rather obvious…!  With the exception of certain people (generally male teenagers), most people have a finite limit as to what they can eat at any particular meal.  Interestingly, we generally reach three stages, with respect to being “full”:

-          Satisfied:  “Ahhhh, that was good and I feel just about right…”

-          Definitely Full:  “Wow, that was wonderful, but I really don’t have room for dessert…”

-          Should Have Stopped Earlier:  “Ohhhhh, my stomach is really uncomfortable – I shouldn’t have had that dessert…!”

How might we apply these ideas to the wonderful world of demos?
