McDonald’s complaint: Foul language between 2 employees over intercom, did not take my order

Pulled up to order breakfast, the employee was arguing over the loud speaker using foul language with an other employee….I continually asking to take my order….there was no response, can I help you, nothing.
I pulled around to order, asked for the manager. Meanwhile the car in front of me, pulled off, mad, left her order. I asked for the manager….what a joke she was! Argued with me there was no fight…..told me to contact the 1-800 number, very ugly attitude, non professional……I will never visit that McDonald’s again! And I will spread the word. These days, with limited employees, I get it…but this manager and situation was uncalled for … but also unacceptable over the intercom. No apology, nothing! So sad….the rudeness this Manger had and showed me and another customer……that I saw. No telling how many other customers left unhappy as well.
