Ronald needs to learn how to speak customers

Hi Mcdonalds<br> <br> I write in this compliant out of great disgust for the manner your cashier guy Ronald spoke to me, We went through the drive through, We bought a family meal and I wanted to pay by my Nedbank American Express, card, the guy said in a harsh tone We don't take American express, I was quite ****ed <br> <br> Please can this matter be rectified as this my last visit
