Complaint Review: McDonald's

i pulled up to the menu to place my order. the worker (maricela) there asked to take my order. after giving my order at the menu there was no response. even after repeating my order several times. i pulled up to the second window and tried to give my order. mericela stood there as if she did not understand anything that was being said. that is called being evasive. next she asked me to write my order down on a peice a napkin. that was very insulting to me because every other customer was able to vocally speak and recieve fast service. yet mericela wanted to pretend like she didnt understand anything in order to portray there being a issue. the only issue was the gap in communication. so finally she went to get her manager. i was given the name elena rodriguez as the managers name. i tried to explain the situation yet elena just evaded my explanations to ask for my order. i told her my order over 3 times right at the window. after giving my order elena would just give me a long suspecting stare. she looked at me like there had to be some ulterior motive behind me placing a simple order. i asked her what the problem was with taking my order. she replied about how i always caused the problem. that is called singling a person out and being biased. it is wrong to make those type of accusations based on her workers' poor service. then she threatend to call the police on me for simply trying to address the customer service issue. she should be fired because that is just uncalled for
