how do fast food restaurants know when you’re there or not, or a car leaves or comes, etc.

Question

I just went through a drive thru and now this question just popped up in my head, and I really don’t see anything that could hint to an answer.

Answer 1

The people working in the drive thru are wearing headsets. There are sensors, sometimes you drive onto it, sometimes they’re just sensors on the sides pointing at cars, and when you go through the sensor the headsets will beep until the worker answers them. There’s also almost always cameras pointing at the cars, so they can kind of see you when you drive up.
