I went through the drive through with my daughter and the Manager who was apparently off duty was standing behind the counter where the food prep was, and brushing her hair. As the server was handing me my change the manager was having a loud conversation with another employee across the restaurant swearing and carrying on. I stopped the server and said "Excuse me what is that all about" The server told the manager to stop and the off duty manager who was wearing no uniform approached the window. I asked her if there was an issue and if those words just came out of her mouth and she acted like she had no idea what was going on. The server appologized on her Managers behalf. As I pulled away she said other obsene things but this time directed to me with my daughter in the car. I am complaining to the Corporation and hopefully there is video of this incident on camers.
