Untrained staff

I am using the PnP app that is integrated with the Smart Shopper loyalty programme and is designed to make access to points and specials (in the form of vouchers) easier than printing these at the in-store machine.<br> <br> However, the staff (and supervisor) at Vaal Mall apparently did not get any training in accommodating the use of this smart technology. This morning I waited so long for a voucher to be redeemed that I gave up on it since the queue behind me was getting too long.<br> <br> Really, can't each teller be equipped with the 3-step guide to performing this easy transaction?
