Nordstrom Rack review: check-out experience

I recently experienced a hostile situation (8/22) upon purchasing a few items at one of my favorite stores, a young cashier by the name of Andres P. not only verbally harassed me but attempted to ruffle through my already purchase bag(s) of items. The transaction number # 3031, and Register# 4903. This young man was not only rude but flippant and condescending; not what I have come to expect after years of faithful patronage with Nordstrom and its subsidiary. I would highly recommend that this young man receive not only enhanced customer training but is removed from the front line operation; he is volatile and appears capable of physically attacking someone. I debated as to whether to formally share this experience but my conscious will not allow me to keep silent knowing that there is a possibility of someone being physically harmed next time. Note, I had to ask the young man to calm down during the transaction because he was verbally combative and when I asked him his name he resounded with Andres, would you like me to spell it? The respond in itself was one of "now what? a challenge". Nordstrom, you can do better with screening your front liner staff.
Somewhat apprehensive,
