Are you a gentleman?
I think basically most singaporean men are not from what I feel.

Of course I don't expect guys to open and close your car door for me,
but I do expect guys to open the cab door for ladies if you don't have a car.

If its date, and its after 10pm, I think a guy should accompany the lady to the taxi stand
and wait for the taxi with her, guys don't need to pay but at least accompany her and wait.
If you offer to pay, that's a bonus, I'm not money minded, but if you can afford guys should pay.
You'll leave a good impression!

Do not leave your date alone, that's a big no!
You ask her out and leave her alone? That's rude, even if you are not interested at least pretend.

I think these are some basic rules no?
