Going on my break

I stood in the express cue at Spar Parow Valley Cape Town and when I got to the front, I took out my items and the cashier, Caren, walking away from me tells me she's going on her break. I was the only person in line, I had 2 items and she didn't have the decency to say "I'm so sorry", she tells me she's going on a break as she walks away. Absolutely no respect
