I'm not sure if they exist elsewhere - but the Mid-West has this little restaurant chain called, "Village Inn".
It's an older establishment I think. They've been around forever.
On certain nights, you get free pie with your order. Even if you order a cup of coffee, they give you a slice of pie.
The pie that is offered is only from a small selection of their available pies - but they are decently prepared.
I think more places should practice this kind of habit. Imagine how much nicer life would be if it included a slice of pie? 
@mentallyalex Did they only bake pies once a week? Because the business cynic in me expects that that's a good way to get rid of excess stock that would otherwise be expiring soon.
That said, it's not a bad practice. Many Panera Bread Co locations donate leftover bakery items to local homeless shelters for similar reasons (or at least they did years ago when I worked there).
No reason to waste good food when people are hungry. 🤷♂️
