The watcher

I was asked to take some pictures for a local hair salon today.
Casual shots of the staff working without being too casual or to staged!!

Anyway it was great fun, several people hated the camera but some really didn't mind.
This chap in the shot has just started so he was 'watching' rather than 'doing'.

I have this look when i'm at work...'no i'm really taking it all in'.

Bad news however: I purchased the 17-40l lens to use but i seem to have a fluffy version. Not at all sharp so i've just sent it to Canon to sort out.
Why me?
