Oh, I had completely forgotten that I did something similar!

To cross the rails, you have to go under them through a tunnel. Someone on crutches took the elevator down while I was carrying my electric scooter and heavy backpack down the steps. I’d make it to the other side before them and could ride the elevator up myself (I thought it would be weird to stand inside, waiting for them), but the person looked like they weren’t having the best day on these crutches. So I walk through the tunnel and order the elevator, but turn around and take the stairs up myself, just as they’re exiting the elevator on the other side so they didn’t see me order it. When I reach the top of the stairs, they just pushed the button and the elevator was right there waiting for them ^^

(As for sending the elevator down to where I know someone will be coming, yeah I do that all the time as well since there’s no reason not to tell the system where it makes sense to go)
