Forgotten juice bottle

I purchased a few items at Ackerman's in Diepkloof square, and when the cashier packed the items, she forgot to put in a juice bottle that I had bought and already paid for. I went back the following day to enquire, and found that she had realised her mistake, and notified her colleagues to inform her when I came back. She had clearly marked the juice bottle "paid" and also informed the security personnel at the door. She took the time to apologise to me.
