Slow bad service

Bad service slow service Bad experience from PEP at Olievenhoutbosch plaza. Long queue with only one cashier assisted. I asked if theres no one to assist her she said no theres no one to assist her with an attitude mind you im a staff member. I requested to see a supervisor, disrespectful lady holding chips with pride we asked her can you get someone to assist you, she literally said what must she do holding her chips with pride eating chappies. For some one working with customers please teach her client centricity.
