Interesting Experiences at the Drive-Thru

Sometimes we go to a McDonalds for breakfast on the way to work. The way this McDonalds is laid out, there is one lane for the drive-thru that splits for two ordering kiosks then converge back together to get to the windows. There is a lane around this for getting around the building. We got in line and got up to the split, but the line wasn't moving so we waited to see who would go before picking a side. Behind us were about four or five cars. We notice a lady in a white car start to back up and go around another car and try to go around us. She got next to us so we went to a kiosk. She had the nerve to honk at us. She was trying to cut! Didn't you get in trouble for that in elementary school?? I just don't understand... what was the point?
