Terrible Customer Service

I had just been sent to the shop to purchase a number of items for various different people, working within our company. On arrival at the till, first, Cashier: Mabel Bosman helped with the first couple items and Cash Back Withdrawals which I required. Thereafter, I realized that I had forgotten to get something. I collected money and change from the till. On returning to the Express Till Queue, I was helped by the same Cashier: Mabel Bosman
