Alcohol or no alcohol it will not affect the next world cup games in any way. The main thing we should be looking up to in the next World cup should be good security , making sure fans should be given the best welcome all through as the game last. I know the host in the next one will give the best to visitors.
in our culture - it is said that the root cause of all the evil is Alcohol.
Banning it helped people helped them enjoy in real time and women and families felt secure as well.
