Receptionist Unreasonable Treats Me

I was delivering books for students on Tuesday morning, I actually arrived early before the dispatch personal arrived so i was forced to go to the front where i met a monster receptionist [ a coloured lady ! which is not the main point here.] When i arrived i greeted her nicely and told her i had Unisa parcels she responded still glued to her computer. I thought she was busy then i gave her a chance to finish without interfering . 5 minutes passed and people came in and were helped by her those who were leaving and entering the offices. Now since i needed to know if she was going to help me or not , i was told that i had an attitude.Still surprised i said to her but i thought you were busy. She said to me preference was given to people who worked for FNB i mustn't come with attitude. Listen here [receptionist] those books belong to the same FNB staff who are upgrading themselves , you don't know what you are talking about. On top of that i personal am a FNB customer , the car that i drive is with FNB my major account is with FNB. And please don't judge people according to what you think. Please request my contacts and see if i am indeed a messenger ,you dont deserve to serve people
