Violently Violated

I am a woman of colour (of African descendent) so I am by no means being prejudice/racist.
I am new to the Metrotown area,today (Sat.26 Sep. 2009) I called around for a saloon that does eyebrow threading and this store was recommend, as it is the only one within the vicinity to provide that kind of service, I was told.
I drove to the saloon and got parking at the back of the building, getting out of my car, there was a sign through an open door that said: "Come in we are open" on a large white metal door. I opened the door because I assumed that this was also the back entrance.
I walked in and the first person I saw was a young black woman (Patricia), who turn around and gave me this stare. It bordered on "you are not welcomed here", I immediately felt uncomfortable and wanted to leave, but I said " I'm in the right place? Is this Ephod?". The young woman turned around and gave this look again and said yes. At the same time another young woman (Poonam?) of persian or indian descend, turn around and ask, are you the one who just called to book the appointment?" I said yes, she said please have a sit. I felt a sense of relief, because I was about to bolt had she not spoken at the time.
The young persian woman came up to me and started quietly providing me with service, I took it she was the quiet type, as I am also quiet there was not much talking except we spoke about what I wanted.
Through-out being serviced I thought I should say something to that young black woman because, if I am paying for service I should not made to feel so horrible. When everything was completed and I paid, I did say something when I was walking away.
I said "Patricia, can I give you a word of advice? please change your attitude, because had this young woman *and I pointed to the persian lady* not shown a friendly face, I would have walked out as soon as I walk in, because you made me feel so unwelcome, and I felt I offended you when I walked in".
The young woman started blasting me with a tirade of nasty words. I proceed to walk away, saying " I did not want an argument, I just wanted to give you and advice that you could use later". She proceed to walk behind me with words feel of venom, hitting the wall with her fist saying, " get out of here and never come back, I will never accept you as a client, I treat all my client nice, I am nice to everyone, if you ever walk into this place again, you will regret it, get off here leave, before I loose my temper and you will know what unfriendly looks like". She walked after me to the point that the young persian woman had to run after her and pull her away, and she said to me "leave, you shouldn't have told her that, she is really a nice woman"

Nice woman? Is that how a nice woman act? If those were her actions, why the surprise or not believe that she was unfriendly. To me a normal person would not act like that. cursing and swearing and pounding the wall with threats is not how a nice person should act and if the manager was in doubts about whether she was friendly or not, Patricia's response is proof enough.

I will never return to that place, and hope that others think twice before going.
