Had a shady experience at Siam Station in Irvine. First time there and never going back. At the end of the meal, the waitress took my card and processed it. Gave me back my card and my receipt, and indicated that the tip was already included. To my surprise, she gave herself a 20% tip. It's a shady practice and not thrilled with being forced tip when table is not even 6 people or more. Owner claims that customers are supposed to swipe their own card and input their own tip amount.
