Having worked in the service industry, I usually tip 25-30%, per drink or per meal. But here's the relevant point: When I encounter a place that doesn't allow tipping, I still want to tip, and make sure to tip, because it's for the worker. I absolutely loathe the new system that's come into trendy restaurants in Seattle where gratuity is supposedly included. That's a skinflint way for a restaurant to raise their prices and assure you that their workers are being paid, without you as the customer having any say (or direct contact) with the workers. You may put up QR code menus and try to isolate the service staff from the customers, and eliminate tipping, but does that make happier employees? Does it make happier customers?

Tipping serves several purposes. One of them is to get the employees to give customers who tip well better service. Sometimes at the expense of an extra ounce from a whisky bottle, sometimes just with more personal care. The insertion of the management into the situation - trying to say it's good for customers and employees - strikes me as a very false, self-serving line of bullshit. And from everyone I know in the service industry, it seems like it quickly turns into a racket against them as well.

My prediction is that by 2025, places that eliminated tipping will be seen as just as infamous as any of the scammy disruptors of the tech industry in the 2010s; the practice of banning tips will be seen as disreputable, and life will return to its natural equilibrium where customers pay extra for good service.
