When I have a great time. I like to give the lady a nice tip. Because I see the same cirlce of ladies, I've noticed different responses. Not that I expect anything from it. It is a gift.
Some are very grateful and often spend extra time our next time. Others, say thank you, but are always out the door right on time.
Am I correct in thinking that all ladies have their own style or routine, and that is what they do regardless.

I think it's the individual personality.
It's always nice if they are comfortable enough to stick around.

A tip is always appreciated... At least that's my feeling.  I've had tips and gifts.  As for spending more time together... I view it as relationships.  As I foster a relationship with someone, and the trust and the connection increases, so does the time.  If I truly enjoy someone's company and am not in a rush, why not hang around for a bit...
