and hope she cancels?

Why?
I think most of the ladies hope YOU will cancel.
Better yet, drop off the envelope and leave!!!

I've made stupid dates "while" drinking lol. If she doesn't cancel I don't have a problem doing it myself. This is business.

...oopsie! maybe not the best idea.

Then I would try to be straight- forward in a kind mannerism, as other prior to be have responded. If it is not a pleasurable time for you- I would thank for you her time for having drinks (pay if she had a small fee for meeting outside) and move on. Not everyone is going to be enthusiastic about every provider and vice versa.
