McDonald's next to Birch Acres mall

Worst experience ever... The manager was called to assist his things(me and my partner) because the "voice box" was not working and the "order window" was closed in the drive through. I asked for the lady to bring the "speed point" to the delivery window and she swore at me... She said "Peter tlao those dilotsa gao" and left. Peter is the manager/team leader. He said the woman's name is Matlala. McDonald's next to Birch Acres mall.
