Very rude security guard

I went to clicks Pmb, Scotsville where I buy all my cosmetics.

I was appalled by the security guard. First of all he was following me (this is not the first time). I then asked him if I can assist him with anything. His comment was “you people *****”.

I am unsure if that is how he is supposed to treat customers. I just walked out of the store and have never returned.

His job does not entitle him to accuse a customer who by the way was carrying a basket of products.
