I know MN is fab at this sort of detective work, so here goes...
She's maybe 40's, slightly husky voice, sharp dark bob with fringe. I can picture her smartly dressed and saying something like "for f*/k sake (insert man's name)". more likely TV than film I think.
Reason being I attended a new yoga class and thought I knew the teacher, but I think she just looks & sounds exactly like this actress, but now I want to know who she is!
