“The rudeness at McDs is the worst out of any of them. Its really ghetto.”
On that, you are correct. I live in an upper-middle class, GOP leaning suburb of Minneapolis.
Our local McDonald’s is obnoxious in term of staffing and cleanliness. The wait is usually too long to get your food.
Gotta say, at the couple of stores I go to near Pittsburgh, the staff is always polite and friendly.
Most of them are young black kids.
A mcd’s close by was recently closed for that very reason...it wasn’t clean!
