Im on lunch - at 4pm - please tell me your secret as i am starved by 8am

On Sunday I dashed in to the Fourways Mall branch for a non slip bath mat. Battling to find assistance I eventually found a member of staff - who politely informed me that she could not assist as she is "on lunch". Its nearly 4pm - why would you starve your staff like that - would be my first question, and secondly, seriously - was that the best response she could give? Not I am on lunch let me find someone who can assist ... or .... or .... Maybe if you did not starve your staff they would be in a better mood and more capable of assisting?
