I'm glad you acknowledged her bahavior and did what you needed to do. I once worked for a company and the owner/boss didn't give a hoot that one of the employees was habitually late every single day. It really got to us (her fellow employees). In time, the business got sold and she got trashed.
At my current job, someone just got fired 2 days ago. NOBODY....should EVER tell an owner, and a profesional Engineer at that, to tell him how to run his business. Oooops! To think they were once upon a time good friends too.

P.S. Hire someone like me. I get up at 3:30am everyday, leave at 5:00 and I am at work by 6am and love getting up that early too. The commute is ok, I pray alot during that time.
