Food and entertainment at $1500 a month? Depends on what you eat!
Go down to hawkers and food centres, and get a BEUTIFUL Laksa or somesuch, and a Coke, and spend $2. Do the same at dinner - $2...
So, living expense for the day? $4. Expensive eh!
If you want to live the Western lifestyle in Aisa, yep, it's expensive, especially alcohol. If you are content on the asian diet, which most are, it's CHEAP!
Only people I have ever heard really complain are SO's, and they usually either share an HDB with other crew, or live at home.
Life is how you make it.
