While bringing items to our storage unit I asked to use the restroom. I was told the public restroom was out of order. The door next to the public restroom read staff only. I explained that it was urgent and asked if I could please use the staff restroom as the public one was out of order. The lady's name was Emily. She was extremely rude and unprofessional. Had she simply said I'm not allowed to let you use this restroom, I could have respected that. But she rolled her eyes and let out a huge sigh. Her entire body language was that of exasperation. It was completely over the top and unwarranted. In the end she still did not allow me to use the facilities. I would hate to take my business elsewhere over her inability to maintain professionalism over such a minor interaction. But I am appalled bit the treatment I received over asking to use the restroom.
