Time is NEVER money in SB
If a SB is charging you for time. Either for your date or for a meet and drink. She is either using you or not a SB. Time is never part of this (other then the I have to be a work at. Or he the sitter is good till.) anyone that wants a gift or money to meet for drinks to see if there is a connection is a no fly at all, no matter how hot or anything. I don't pay to sit at a bar to have a conversation. I can do that at any bar.
Also do you ever meet up before discussing that? It is a waste of time if they want a fortune and you aren't going there, but sometimes they could be hotter than their pics. And I suppose not always bad to meet someone for lunch, but time is money and not my favorite thing to do.
