I almost never go to restaurants where the tip is automatically added to the bill. I’ve had 15% tacked immediately to our bill when the waiter was an a-hole.
Almost never, unless the other party or everyone chips in but I have cheapskate friends and they even balk at it.
We try not to go to restaurants that do that either, but more and more are doing it. Hubby likes to put no tip on the payment slip and then tip in cash at the table. That way he thinks the person that waited on us gets the tip. I think it still goes in the share pot if the restaurant has a shared tip policy.
