This should not get a star
The obnoxious owner was acting like a complete jerk. And was rude. He would not honor an Entertainment book coupon.
My wife went there and gave owner her coupon for 25 per cent off if you spent $20.
She did and gave her a hard time.
He said he did not authorize it. And would not honor it. In the end he honored it.
Buddy you are in a service industry and rely on good manners to your customers. Don't forget that.
