McDonald’s complaint: MCDONALDS employee were Drunk while on their job

I have a complaint regarding MCDONALDS on DOOLANDELLA QLD AU. On February 19h, at 11:35 p.m., we went to this McDonald’s for coffee. When we arrived, the employees were highly drunk and stood outside the door, shouting so loudly that the lady at the counter couldn’t hear us. However, we requested to speak with the manager named Jeff and reported this incident to him, but unfortunately he was too drunk to understand our request. We enquired as to why he permits employee to become drunk while on the job. When the manager was making my coffee, one of those drunk employee stepped inside near my coffee talking and blocked our view to see what she was doing with my coffee. We didn’t discuss it further with them because of our safety, but we didn’t drink the coffee because it smelled horrible as well as we didn’t trust them.
I am happy to provide proof my purchase upon request.
