Inappropriate behaviour

Date: 02/02/2019 Time: around 17:00 A friend and I we were at Windermere Centre Checkers and it was our turn to pay the cashier's name was Collen/ Collin but around there a male in his 20s . Then he gets up from his seat so I ask is there a problem. He then smiles confidently and said "Ya one of my ***** sat funny" in IsiZulu.

I have never been so horrified and I said "wow" he then proudly rep**** "Its the truth, I am telling you the truth I am being honest". My friend walked away mortified I paid before I walked away I said to him "You do not talk to people you don't know like that and it is unprofessional" and he could see that I was not amused - he did say he is sorry.

I do not know where he got the audacity but I sure as hell would appreciate if staff is made to understand there is a line and we are not their friends. My friend and I are both on the second half of 30 I don't know if he was being flirty regardless when we come to a shop we are not there to be hit on this left a horrible taste in my mouth. Maybe now we should avoid male tellers.
