Ross Dress for Less

Went in today to shop as as soon as they opened. I ran to the back before starting to shop to go to restroom. While i'm in restroom employee comes in and tells me I have to ask permission to use the bathrooms and was not supposed to just come in and she was trying to clean. I did not see her when I went in the restrooms and they were open and did not have any kind of sign on the door. Have shopped there before and have never had to ask permission to use the restroom. I just left after that incident and will not be back.
