Totally agree that there should have been more at the ground. We were surprised because we thought celebrations would have continued on after the players left but with nothing happening everyone obviously just headed for the club.
I actually thought the idea was to keep everyone at the ground to alleviate crowding at the club. If this was the case then further entertainment and more food/drink venues should have been a no brainer.
You do bring up a valid point. But there probably would've been a million complaints from the local residents if the club/council decided to do that.
