To be fair, this forced friendlies I have found in many restaurants and bars in the US. A very annoying behaviour. But apparently, people over there will complain if the waiter has not been around annoying them by asking if they need something else all the time. Workers are already being forced to put up such a show because customers like it. I don’t think the problem is using AI to check this, but rather that this behaviour is being forced onto workers in the first place.
