If you dont love your job then Quit

I went to Pic n Pay Hyper in Greenstone mall, to collect my colleagues grocery from customer service so that I can pay for it. I was informed that she did leave her details with the lady assisting her. As I arrive there is a pic n pay employee who was assisting there ,as soon as she was done with the gentleman, she proceeded to leave the service area. First of all she did no acknowledge my presence as a customer, I had to greet her ,I asked if that trolley that trolley was perhaps my colleagues as there two trolleys there. She looked at me as if im speaking Chinese, she answered that she doesn't know, she doesn't work by customer service and doesnt know who is working there. As she is talking she is walking away. She was so rude to me, I don't remember when last I was treated like that, I asked her to find out who can assist, but she didn't even look back. So there I am waiting like an idiot, no response from her at all. maybe its because I was wearing my uniform because im also working at the very same center for a different retail store. I jus continued with my own shopping and left the trolley for my colleague to collect it herself, as I was uncertain of which one belonged to her. The pic n pay staffr member is Sarah and she is acting supervisor, she is short and dark in complexion. I was there around half past two on sunday 28 may 2018
