I walked into a McDonald's this morning in lieu of taking the drive-thru during a coffee run (drive-thru was packed).
I must have wasted about 10 minutes in there as there was confusion over several coffee orders containing two creams, three creams, and double doubles. The staff mixed the wrong ratios into the wrong sized cups and couldn't figure out how to untangle the mess. Customers were looking on perplexed and some folks were starting to get agitated, including the staff who didn't understand why nobody was picking up the large double double (which should have been a medium double double).
Have McDonalds changed the way they operate? I visited two different McD's in the US and you don't get your food while you stand there and wait they give you a plastic number sign you put on the table and they bring the food to you when it is ready.
