This will be out of topic. I have been away from SG too long so I am curious why guys in Singapore keep complaining not enough money.
U might want to contribute on this "why".
In this case, single guy.
Let us do the math here. Estimate on the higher side.
Public Transportation, 10 per day, 30 days = $300.
Food per weekday, 15 per day, 20 days = $300.
Food per weekend, 50 per day, 8 days = $400.
Mobile bill and others = $300.
Give parents = $500.
Total = $1800
Most guy with a basic degree should be able to take back home smelly smelly $2000.
