Hans,
Your right, that's just crazy rates!!! In the office there should have been no charge whatsoever, There they would have still been under contract with their client your lady!!!
I don't think i've ever heard of anyone here on the Forum being charged for translation while in the agency premises.... Some of these agencies really do try and milk the cow dry. They never seem to be able to see the bigger picture, ...just the here and now!!!!
David......
