Have you not been to a drive through lately? Plenty of ‘computer’ help with the ordering experience.

I’m sure most fast food places would love to operate sans employees.

The strangest thing is happening at my drive through, the voice sounds to be of an older woman and when I get to the window, there aren't any woman working in the restaurant.

There are many non native worker in this restaurant with a distinctive accent but this "old woman" has a local accent.

It's not an ai voice so my guess is that she's somewhere else (at home?) and only handling the drive trough requests.
