What Is It Called?

went for dinner last week at Taman Billion in Cheras last week and notice something new on every table. it has 3 buttons on it. water, bill and call. find it to be convenient as you just need to press a button in order to get them over. just press the bill button and they will come out with the bill in a minute. well, it's good that at least we don't need to look for an available waiter and get their attention should we need anything.
