Answer to original post title...
It's just like the difference between the way people eat.
Some people are just hogs. They don't care who they eat with, they overstuff their mouths, don't chew properly and race to see how fast they can pack it away only so they can obsess about what they will eat next.
The rest of us savor the flavors, enjoy the experience and the people we dine with. The longer it takes usually the more happy we are with our meal.
Perfect analogy for this thread.
