I've absolutely lost count of the number of times I've been mugged off at the drive thru here. Don't get me wrong, everyone makes mistakes and I'm sure the staff work hard - but there must be some sort of check system in place against orders. My particular highlight last month was going to the drive thru on my home from work and ordering a double big mac meal - been wanting to try one for ages - with a choc shake. Not only did I end up with a vanilla shake instead of choc without being told, they never gave me the double big mac! Totally excelled themselves. So my double big mac meal with choc shake actually consisted of fries and a vanilla shake. I even double checked my receipt to make sure they'd heard my order correctly - they did, they just didn't give me the food. Tried phoning and left a message, their voicemail said they'd call me back. Guess what? Never happened. Now we're never gonna stop going to McDonalds, but if you use the drive thru, stop in the car part and check your order before driving away. They mug you right off when they can.
