Racial Slurs and Insults by manager

My son and his friends had such fun celebrating his 16th. The only disappointment was my encounter with Geoff the manager, the temperament and attitude he displayed while I was just inquiring abt our balance shows poor customer service skills. He started swearing, insulting and uttering racial slurs. He pointed a finger at me threatening to beat me in front of his stuff. They had more than 500 bucks on our account and wanted to know wht we could get for tht amount in the bar. He said I had 2 minutes to order drinks and drink them there as they were closing. His pple skills are terrible.
