Completely ignored at Express Shop

This morning, at around 07:50, I arrived at a BP Express shop in Fourways, just outside Fourways Crossing. I took a few items and went to the pay station to pay. I greeted and put the items on the tray. The lady behind the glass didn't even acknowledge my presence. She continued to talk to the other lady behind the glass. I said hello, and was ignored. I said it again louder, and i was ignored again. I left the items on the stray and walked out. BAD ATTITUDE SO EARLY IN THE MORNING. Never going back there again.
