If he shows up, he gets paid. If he doesn’t, he doesn’t.
I’m a contractor. If I don’t show up, I don’t bill the client. I think most would be little surprised (just like you) if they knew I didn’t show up but still billed them.
Based on some of the responses here…I wish I had some of you for a client. That way I could just bill you for the 2 weeks while I’m gone on vacation.
