I agree with you Steve, but what if the Lady ask you to stay bit longer on her time, she insisted on it. It hard then to be rude and say no it ok, as it could come across you can't wait to leave their company. I have been ask to stay bit longer and have also offer to pay for it. But told no it ok as it quiet and usually late booking I do. I even got ask to stay a night over in Lady company on her time. To which I won't say if I did or not
but it did brought the idea of overnight to my mind
But yes don't abuse the time you have and sometime it can't be help if both are so carry away in moment of fun
Call it good chemistry and connection
