I agree with you. Last time I was there, many years ago, still a college kid. Me and my friends were there for some drinks. It was around 8pm, not many customers at that time. After we got our drinks, and a friend got her food, we ate and chat. 20 minutes later, the bill came to us and we didn't even ask for it. We took it as a gesture from the waiter to ask us to leave as soon as possible. We weren't happy that time.
