Worst Manager and Service

I am a regular customer at Mcdonald ‘s Malboro. I usually buy Cappuccino. This time I bought tall Cappuccino and it was half, mind you this was the first time. When I asked, I was told I must be grateful that I got a well trained barista because that’s how it should be . The manager cannot even resolve a simple complaint but she will gaslight you and take Zero accountability. Her name is Patience
