McDonald’s complaint: Very disrespectful and vsry unprofessional

I placed my order. While i was ordering i noticed the cashier made a mistake so i repeated the order and noticed it again so i repeated it again and the cashier made another mistake and had to get the manager to correct it. ( Now in my order i ordered 3 chocolate milk shakes). As i waited for my order i noticed them making a shamrock shake and told them that i ordered 3 chocolate milk shakes so the manager said wel u have to pay for the chocolate shake after i already did and i tried explaining to him that i already did but instead of chocolate u gave me a shamrock shack and he refused to just make it chocolate and made me pay for another milk shake so i was just not in the mood so i did buy another chocolate shake. So once we got done with him being very ignorant and cocky i recieved the milk shakes. I then asked for a straw while i waited for the rest of my order and the manager who i wasnt even asking for the straw from cut in with a very disrespectful attitude stating youll get the straws in your bag. So i just ahrugged it off and waited for the rest of my order. Once i recieved my meal it was wrong. Now remember i repeated my order 3 or more times. So i said to the manager that the order was missing a medium french fries he proceeded to argue with me saying that i never ordered them. Which agaian i repeated my order to him and he proceeded to cut me off and say that i had to pay again for the fries. At this point im getting really mad and say screw it i dont want them but an employee that watched it all was going to give me the fries but he snapped at her and told her that if i wanted them i needed to pay so i just started to walk away and so then my friend stood in line to buy another fry for me. And as im leaving another customer had a mistake with his order and the manager then started being very ignorant and disrespect ful to that man so they argued and he walked out without his order cuz the disrespect the man had to deal with. So i had to pay for a molk shake i didnt get and a french fry that i also didnt recieve.
