Untrained staff

I have experienced the same issue twice at a Pick n Pay in Kempton Square.

The store has recruited new cashiers since Dec and I believe the staff was not trained because for 2 times I have had to explain what the QR scan option is. I have had to guide cashiers in using this option.

It shouldn't be a customers responsibility to train staff on behalf of the store. The cashier's are even confident to say, they don't know this because they are "new" Training frontline staff should be a priority of a retail store.
