Go early for 'Happy Hour' to avoid spending full price on all your drinks?
Seriously, the only other thought that crossed my mind, which I'm sure you have probably tried, is to try making sure Alice is alone in the nightbar. Can't remember the days, (probably mid-week) but sometimes going to the nightbar when it first opens at 22:00hrs, there is no one there. If you don't have a 'save' prior to that, roll back and go visit Alice and arrange for her to meet you.
Again, that's just a shot in the dark, but it does change a variable and who knows what might happen.
