Arby's locations in Springfield, MO

Waited 10 minutes for my order to be taken when i finally say something get told to hold on, 2 minutes later I order 2 for 6 beef n cheddars with extra cheese and cheese sticks which i had to repeat twice, get to the window and wait while the manager finishes her personal convo, cursing up a storm. Get my food, they arent extra cheese. I go back around, wait again tell them that i got charged but didnt have the extra cheese she calls me a liar and opens it up to check. Has them remade and then tells me again that they WERE extra cheese, I apologize and said that usually when i get regular ones they have more, she calls me a liar AGAIN and I tell her that I think its unprofessional to say that to me especially after I waited so long and listened to their personal conversation before they opened the window and then two crew people come up to the window and one says "what you never have fun at work?" And the other swears they werent cursing and I let them know I could hear them and told them the portion of the convo I heard and the manager slams the window in my face. Im disgusted. I wont be back.
