A customer told me that she was at the neighboring shop and once it happened that the cashier accidentally knocked down a can of tuna. It dropped directly onto her toes and it hurt.
Never mind about that. What's not excusable was that the cashier didn't even say 'Sorry'.
From then on, she has stopped visiting that shop and started coming to my shop.
I simply asked, 'How about us?' She showed her thumb up and said, 'You people are good!'
Wow, I felt so good..
