"The wage never quite reaches the us$100 per week figure, by the time the government raises it, it is usually in the us$50 to $60 range."

Very sad. We spend more than that on a nice lunch. This is why I always tip well. And before I hear comments from the tip haters, yes, I tip everyone I come in contact with from the gardener on up, and this applies wherever I stay. If we can afford vacations like we do, the least we can do is help those who help us enjoy ourselves.
