McDonald's — Restaurant in Billerica

First and only time I will walk into this place was today. Where do I begin....Rudeness and incompetence of the staff. (You have ONE job) Just went for a drink with my Fiance. She ordered a Medium Slushie I ordered small Ice Black coffee. Seems simple enough. No, it wasn't. I was told they don't serve small Ice coffees by the Asian Woman working the register. So I said medium is fine. She said hot or cold. Ice usually means cold, no? Then she asked cream and sugar? Caramel? No. Black coffee is black coffee. My Fiance ended up with a small smoothie. On the SMALL smoothie cup it said coffee which is weird because I was told they don't have small ice coffee. Then we ordered from the app A chicken nugget with a free medium fry as they do on Fridays. They brought the nuggets but no fries. The Manager brought them and was beyond rude and dismissive anytime I tried to explain even showing her what I ordered from my phone to the point she threw a small fry...not a medium in front of my Fiance along with literally slapping me receipt on the table saying "see? No fries" Miss, I'm not trying to get over on you with free French fries which they offer free on your app. Once done, the Asian woman came to our table and tried giving us someone else's food that was sitting on the counter when we literally just ordered and ate. I don't get it.

ONE job. ...

McDonald's is ok. They messed up my order that I made through the drive through. The girl told me to pay at the first window. I drive up to the first window and there is no one there. I drive to the second window and tell the girl there wasn't any body at window one like she told me. She didn't apologize but said, "Oh. There is usually someone there." On top of that, I ordered two medium fries. The girl hands me the bag and starts walking away from the window. I look in the bag and realize I'm missing a medium fry. I had to shout through the open window to get the girl's attention and tell her I'm missing a medium fry. She had to check the order screen and talk with her manager to see if I should get the second order of medium fries I ordered and paid for. The manager shoved the bag of medium fries into the girl's hands and the girl handed me the bag of fries. ...

Had a real bad experience with the Drive Thru couple of months back in the evening. I was asked to park and wait for my Filet-O-Fish orders as they just started to prepare with new filets... I went where I can park and not block the traffic. I was waiting forever but no one came with my orders. I had to go back to Drive Thru in person (as getting into McD wasn't possible, it was closed for some reason). I got my order but really had very rude interaction with the service person. She asked me why I did not park where I was told (if I parked where she asked me, it'd block the Drive Thru and so I did not park there but parked within McD parking area). She also said I can't stand there in Drive Thru but standing there was the only option for me to get my order. No thanks to her but her service was just horrible.

McDonald's, what's wrong with your...
