We definitely hand the cash tip to the waitress/waiter. We want to make sure they receive all of it.That's great. I guess in the future I'll put the cash in their hand before I get up. I may go in there again. I don't want to be seen as some weird grumpy no tipper when everything was good enough.
I probably could have handled it better by talking about it, just assumed she would look and see there was cash on the table. Hell, might be time to be a full cash guy. ATMs around me limit to 200 a lot. That ends up being a lot of cash runs with prices these days.
To be clear, we only tip like that at sit down restaurants.
