Disrespectful Staff

Yesterday I went to Checkers Kolonnade to the Medi-Rite pharmacy. I greeted the lady (Martmari, not sure of her surname) behind the counter and as per usual she doesn't greet back. I asked if they had any masks and she rep**** very irritated with me with "ja wat van dit". This is not the first time I have been treated with no respect and decency from this lady. She rarely greets me, everytime I am being helped by her she has a attitude towards me and I can see that she doesn't have the time and energy to help me, a paying customer. I have never received this treatment from any other employee at a Medi-Rite pharmacy to date. Never the less, I will from now on be taking my money to the Clicks or Dischem nearby as I don't want to be a bother for Martmarie at Medi-Rite Kolonnade anymore.
