Are Customers really a priority ?

I had a very disappointing experience at the iStore in Mall of the North. While I was at the till and the lady was already helping me, she started chatting to her colleague about something else instead of finishing my transaction. I stood there waiting, even though the store was empty. When I asked her to please help me first and talk to her colleague afterwards, she gave me attitude and seemed annoyed that I spoke up. Very unprofessional service — customers should be treated with more respect and attention.
