Just checked my phone messages as I had my phone off as I was working.
Turns out the first gig dropped Monday - Wednesday after all, and want to push for Thursday, which I can't do. And for some sporadic days the following week.
I will call tomorrow as it's too late to call and find out what the story is and inform her that Thursday's a no-go.
Meanwhile, I had not put in for a certain gig because I thought I was booked for Monday and Tuesday. I put in anyway, even though it was rather late.
This sucks. We'll see what happens next.
