Bad customer service

Visited McDonald's in mayville and the experience is very bad this was a second day I been treated bad with the same cashier named Smith C - Crew ID 247. My order number is 3286. After I placed my order she gave me a damaged coins as a change and I kindly asked her to replace it as I was not okay with it, she responded with a bad attitude and shouted forgetting that I had paid with a good money. If what this cashier is doing is what McDonald's values stands for, I will encourage people to stay away from this mayville outlet.
