Rude Staff

The teller Gugu very rude. Gugu you need to learn to bite your lip at times. You not at home now but at work so play professional not dumb. I wasn't able to use my store vouchers as she processed everything already, including payment and never asked if I had any vouchers I wanted to add. How am I suppose to know how your system works? I'm a customer and not an employee there, so don't give me lip.
