This is so fucking stupid. I've worked in hospitality, saying please and thank you just comes with the territory no one needs to be checking if you do it.
In a cafe that's the whole service (in my country at least): being friendly to people, and providing a nice place to hang out and have a coffee, the actual beverage is secondary.
Saying please and thank you is such base politeness. You can easily be rude or cold even when you do use them, and conversely, be absolutely lovely without using them at all.
People don't go to burger king for the pleasantries, the amount of politeness you should expect is the same as anyone else walking down the street.
Policing politeness with technology is stupid. People should ask each other how they're going genuinely. Not from a place of corporate greed.
Fuck this capitalist dystopia.
