Bad attitude

I came to your beacon bay branch to do an exchange and your cashier called for a supervisor.The supervisor came giving the cashier attitude in front of me like y the hell are you disturbing me.It seem to me like customers are a pain to your supervisor which gives her more work.If this is what you call service then sorry to say I will definitely not be visiting your store again.If ackermans employ people of this calibre then no wonder the service levels is pathetic .
