People are fine with closures in off season, it happens. The issue is closures in off season is normally 2, but max 3 majors at a time. Not SIX.
This is like going to timezone, loading up a 2 hour unlimited game card and then finding out that all they have is whack a mole and ski ball. It doesn't matter that it's midweek outside of school holidays.
This is going to KFC and they tell you they're out of chicken after you order and pay for your meal. It doesn't matter that its 11am on a wednesday
This is going to the Cinema to see Sound Of Music, but all the songs have been edited out. It doesn't matter that its cheap tuesday's morning session
