The problem near me is that basically every restaurant is doing it, avoiding it would essentially mean avoiding eating out.
This practice is becoming widespread in the Bay Area, and I saw this in Boston earlier this year on a business trip (and what made it worse was that the particular restaurant I ate at didn’t announce the fee in the menu; it wasn’t until I saw the check that I saw the 4% surcharge). I refuse to dine at restaurants that charge “kitchen fees” or “service fees.” There are still restaurants that don’t engage in this pract…
If you add a 4% kitchen fee to the bill, my typical 18-20% tip becomes 14-16%, exactly the same as if you added a "parties of 6 or more have an automatic 18% service fee" then my tip becomes 0% (on top of the 18% you're already charging me).
If you try to sneak in a 4% fee that wasn't disclosed, let's just say that my tip changes, but does not become larger, if I discover your deception.
