How much do you tip when you pick up food to go from a restaurant?
Clarification 1: I'm asking about when you place a takeout order at a restaurant, and you yourself go to pick it up. (i.e., this question isn't about tipping your UberEats driver).
Clarification 2: this is about casual to fine dining places, NOT fast food joints (McD's, Chipotle etc). For example, lunch at a locally-owned hipster salad and sandwich place.
Bonus question: does your behavior change when they flip that order screen back to you, and the "beg button" options show 18%, 20%, and 25%; with a tiny button that says "different amount"?
