Rude Cashier

I went Chatsworth Centre PnP, I got a few things and stood in the express que. It looked like I had more than 10 items but the cashier just rudely directed to the other que - she didn't bother to check first. I was so shocked at the way she was responding to me I left the store without paying for the items - I left. Worst part is she is stationed across what seems to be the managers/supervisors desk. What a disappointing experience.
