Bad business owners

I really do enjoy their food but i’m really annoyed that you can’t even give the waitress a TIP! Our waitress said she can’t accept our tip because they aren’t allowed to get tips anymore ? what’s that all about ?? That’s horrible from the owners side , THEY ARE YOUR STAFF !! THEY ARE HELPING YOU IN YOUR RESTAURANT AND WORK REALLY HARD ! They don’t deserve that “no tips allowed “ ABSOLUTE BULL
