maybe not.  It does make you wonder though.  However, actually I totally agree with your policy.  Shit happens. But really she should have stayed in better touch with you regarding her delay status.  That's the main issue I would have.  

I actually met my new ATF again this evening and originally we scheduled for 3:00PM.  Then she texted me and wanted to change it to 5 or 6 PM.  So I change my plans and then she contacts me again and says she could do 4:00PM which we did.  Do I blame her?  Hell know.  But she also did a good job keeping me informed.  Also, I know her well enough to know she was delayed at her real job and why she was delayed.  So I could rest assured it had nothing with needing extra time to clean something out of her hair
