PostHog here is saying they will train on your data but opting out is allowed. For the taxes analogy to work, PostHoh would not offer the opt-out option at all and you'd be doing something like hacking their system to filter your data out on their end.
I've taken to a) leaving a negative Google or yelp review for such establishments and b) never coming back. This is a practice that needs to die.
But at what point do we call a spade a spade and say it's just them secretly inflating their prices? "everything is a penny but we charge a 1000000% service charge"
I'm talking about restaurants that just add service charge to everyone.
There are a fair number of well-meaning restaurateurs who have tried no-tip policies for ethical reasons. But the mass marketplace has not changed.
The average consumer can't do math.
