Subway complaint: Rude bad attitude manager

Each time my family and I go to subway 2 times a week. The manager her name tag is Cissy she is rude with a super bad attitude towards customers. That’s if you can get her off her phone to help you. Them she really is nasty towards people. I have actually witnessed customers walk off because of the way she treats them. I love going to Subway in my family loves it we live in a small community Subway’s only restaurant in town but it is to the point I don’t even want to take my children and they’re to witness the attitude like that. She is also telling employees business to other people and I thought they was a privacy act on that? She just don’t seem to be cut out for a manager position cuz she really acts like she does not know what she’s doing she’s talked to her employees like dogs in front of the customers. I don’t know what protocol for dealing with stuff like this is. But I would really appreciate this being addressed .
