I was just there a few days ago.  I ordered my daughter a kids meal thru the drive thru.  The women at the first window was very nice and professional.  When we drove to the next window to pick up our food the women just handed us the juice then handed up our kids meal.  The whole time talking to fellow coworkers.  We saw only the back of her the whole time.  No hello no thank you or anything.  It was the weirdest thing.  My husband and I were shocked that happen.  Sorry Mcdonalds we were bothering you.  The funny thing I think she was the manager because she was wearing a different color than everyone else.
