As far as I can tell, they're at least supposed to use location services to start the order when you're nearby. When the store isn't super busy my order is typically ready when I arrive, and I've ordered 10-15 minutes before arrival a few times and my orders weren't cold.

Maybe this is what they're supposed to do, but the system and/or employees don't do it reliably.

Or perhaps it's because I typically do counter pick-up, and almost always have a small (1-3 item) order.

It makes sense that they wouldn't prep your order if you're just going to be waiting in a long drive thru line anyway, though this could obviously lead to further delays because they don't reliably have larger orders finished in the time it takes to get from the speaker to the pick up window.

I've only used the app a couple times so I only knew the first half of that.

I can enter an elevator is under a second and push the button. This is doubly faster when not waiting for the doors to open fully, effectively making my button push at 0 seconds from door full open.

If you're saying "3 seconds is not long to wait, so it's the same as the button doing nothing", this is false, untrue, and I often use it.

Alternatively, requiring elevator door to wait 3 seconds as a default does not negate someone overriding that.

I've manipulated the button and seen timing differences. It does work. It does make a difference.

Did you mean something else?
