So I went to Wendy's to get an iced tea, and found myself behind folks with most bizarre idea of how drive-up service works. Two cars were side by side at the ordering window. The car next to the window seemed to have finished ordering. Both cars sat adjacent, yakking through open windows, until I honked for them to go up to the pick-up window.
They pulled up next to each other at the pick-up window. The Wendy's server handed a bunch of drink cups and bags of food to the car at his window. In turn, about half of these cups and bags were passed over from the passenger side of the one car to the driver of the next.
It took forever.
When they finally left, I pulled up and asked what the heck that was all about. The cashier said it was the dumbest thing he'd ever seen. Not only did they do totally goofy two-car ordering, relaying orders from the car on the right through the car on the left; they also asked to have everything repacked into separate bags to match the two cars.
You know, for 99.9% of us, our drive-up window thinking is just so linear.
