Some of the employees at this McDonald's are very rude. I went there for breakfast the other day. When the lady opened the window in the drive thru to give me my food I said hello and she just handed me my food without even saying a word and then closed the window.
Similar situation when I was there after midnight. The cashier working in the drive thru said nothing but the price of the food and looked at me like I was an inconvenience. She was probably mad at me for interrupting her smoke break since I saw her outside smoking when I pulled into the parking lot.
