employee swore at my wife and I

Sunday morning on our way to church we stopped at McDonalds restaurant #17792 on 08/09/2026 at 0847 AM. We tried to order throught the app but were told that the computers were down and we couldn’t use it. We ordered anyway and we were asked if we wanted cheese on our breakfast sandwich and I asked why are you asking me this as the sausage and egg McMuffin always comes with cheese. I got a muffled response through the speaker and asked for clarification on the order. When we picked up our food the kid was asked if there was cheese on the sandwich and why they were asking if we wanted cheese. The kid told me to “fuck off dude” and slammed the window shut. I then called the restaurant using my mobile phone and the same kid answered and wouldn’t let me talk to the manager and would not give me his name. We are 80 yrs old and having some pencil neck punk tell me to “fuck Off” was not appreciated.
