One rule for one. One rule for one other!

One rule for one. One rule for one other!
Sadly one person for the past 2 years has ruined our fun.
We didn't expect to see this guy here again, must be a regular!
He completely takes over the dodge ball.( not manned by staff)
He is a grown man that seems to get complete pleasure at throwing balls with all his adult strength and anger at kids.
This year he really hurt my daughter and she was bruised on her leg from the force of his throw.
I witnessed 2 other children cry and limp!
Even my 13 year old with his bday friends didn't want to go in the dodge ball and neither would I.
Why on earth is this allowed to happen!
Kids can't kick a ball but he is allowed to intentionally hurt people.
Interesting that when I mentioned this behaviour to one of my friends they had encountered him at there visit and said they wouldn't return as he ruined there experience so goodness knows how many others!
We have done air hop for the past 4 years for my son birthday, will defiantly consider going some where else next year for his bday if something doesn't change!
His behaviour is more dangerous than the rules you apply!
Please address before someone gets hurt and why should other people not be allowed to use this part of air hop coz of one person!
It's like stepping into a lion den!
