Here's the tip reform I want:
Every restaurant/bar/etc with their staff decides on a default gratuity that represents their service standards/aspirations.
Menu prices must include this gratuity. (And include taxes - why not.)
At time of payment, the customer can choose how much they want to tip: the default, or some amount more or less.
Transparent prices. No unwritten rules. Bar staff still make $$. And no disadvantage to restaurants who pay a higher hourly wage instead of tips.
