I would say that the financially prudent will not even go near a casino, levy or no levy.
That's not really true. Over the years, I have happily milked unlce lim's hospitality while hardly loosing any money to him. If you add up the free rooms, food and drinks, I think I have definitely come out ahead.
Most people think it is crazy the way I play so I have long since given up trying to explain it to them. If I have lost money, it is more to friends who make me buy them lunch on the long drive back.
On RWS, I wouldn't pay $100 to go in. Why would I when I can get a much better deal going to Genting? For that same $100, you can get a room for 3 days 2 night. You don't have to jostle with an army of freeloading foreign workers and you most certainly don't have to queue 20 mins to use a dirty toilet.
Anyone who cannot do the math and go to RWS obviously deserves to lose.
