Most Utterly attitude it is disgusting

So i brought my brother for an interview at Farenheit Management at Sandton, i went to the reception and i asked for a bathroom, in the bathroom was a lady the she was filling in her "timesheet", greeted, got in to do my business, came out, washed my hands and as i was drying my hands the cleaning lady open the door half shows her head look me right in the eyes foe like nice 30sec looks at my phone and car keys at the counter and looks at me again without saying anything....her face was sooo scary like I am not supposed to be in there.....then she shout ,you see what you did to the mirror, and the I turned and looked at the mirror, i am SHOCKED , I DONT KNOW WHAT I HAVE DONE TO THE MIRROR AND SHE KEEPS ON SAYING I FKED UP HER MIRROR WITH WATER, and my hands, i told her that 1st of all she stares at me and that us rude, she is making me uncomfortable in the bathroom I need my space , it is her job to clean not mine, she is DISRESPECTING ME IN THE BATHROOM out all this places....that is bit how she must speak to anyone if not at all....I told her that i respect her as a person she MUST respect her own job and if ahe has a problem with that she will loose her job, she does not take her job seriously, she undermines me as a black person and i can bet that if i was of a different colour this would never have happened. SHE DOES NOT DESERVE TO WORK AT YOUR COMPANY NEVER MIND AT ADF GROUP. I have to get a response for this utter behaviour
