Haha, your friend do what?

If go there now, you're not pr, wont deduct CPF confirm can save around 1k.  I started out 2.7k, rent shared room, eat kopitiam food save 1k everymonth. Shortly after, switch job, earn 3k, rent single room, food eat mall food like long John's, mcd, burger king, still save around there.

If your friend expenditure cannot save much with 3k in sg, i doubt can save much with 5k in kl either..
