One word: Balance
You have to be able to differentiate between when you're being nice, and when you're supplicating. When you're being a jackass, or when you're standing up for yourself. It's a dance, it isn't just black(all jerk) or white(all nice) it's a whole lotta gray.
I look at it another way. It's not about being a nice guy or a jackass/jerk. It is about attraction.
By all means, open doors for them, hold out seats for them, etc etc, as long as you generate attraction (there are enough posts littered around the forum on the topic).
