Shoprite Bluedowns Cape Town -Horrible Customer Service

Went to shoprite in Bluedowns Cape Town just to get 3 items, after a long day at work. However I just have to say that customer service in a suburban area sucks. The lady at the wouldn't assist us when we only had 3 items and we had to go back and stand in a very very very long que. What would have taken her 10minutes ended up taking 20 minutes. I do understand that the staff in retail works long hours, and sometimes are disrespected at times I just think its also their doing. Why should I stand in a long tedious Que with but 3 items.
