Idk, they've all been wanting these kiosks to take off for a long while - maybe ~10 years - and it's just a UX problem keeping most people away from them. Given the labor savings at stake and the simple availability of speech prompted data entry, I'd think they'd take it more seriously.

A dumb easy solution is to just create a call center of sorts and allow the same voice interaction human-to-human while the other person enters in your commands quickly and you just pay the kiosk at the end. They could have done this with very little investment in technology. Could improve the drive-thru experience too (my experience is they can't hear anything you say, I'll have to repeat myself 3x minimum, and chances are I won't be able to understand them if they ask me anything either).

When I visit Shake Shack, it's the one place I see that the kiosk is mandatory. But, at least they are iPads and decently designed. It's still very tap heavy and slow to enter simple customizations. The main thing they did right was put 6 of them out, so it's rare you have to wait for one because if you do have to, it's probably a long wait. It's also when one of them will step up to the register and start to help alleviate the line. The worst thing they did, was prompt for a tip at the self-service kiosk before you've seen your food or even found out if anyone is actually working back in the kitchen.
