Elihle-Bad Service

I'm not happy with the service received from Elihle this morning at Spar The Wedge, I'm sick with the flu and my nose and ears are blocked at that time of the morning. As I was paying she shouted at me and gave me so much attitude emphasizing that she's greeting. My friend and I ask why she's shouting and she says she's greeted twice and we didnt respond, again with so much attitude.
