I remember years back  before I knew about sport betting; there was a football viewing center close to our house. The noise and jubilation that comes out from there always makes us wonder why people love football so much. Not until I realized the shout and jubilation was because people placed bet on those matches.
So, it's not like they are happy their favorite club won but because they won. 
Do you get excited because your favorite club won or because your ticket won?
