On drive through I will take orders while I’m at the oven or whatnot and repeat it back to them as I’m walking back (or in hopes of someone else popping over and plugging it in). If I’m doing both dtr and dto it’s all about timing.

If you have a car pull up to the window and a ding at the same time, you can answer (hey there, welcome to Starbucks what can we get for you) click off, open the window (hi there it’s 5.45) take payment or scan app, duck in, key in the order while simultaneously running the card or grabbing the order (repeat it back, great, I’ll see you at the window) click off, back out the window to hand out order, etc.

Usually you can get a good rhythm going so no one has to wait more than a beat.

As for bar, keep practicing your sequencing. It takes a while but it will click.
