Suetheramble : I�m saddened to read this. The simple truth is that your daughter ought to have received every single gratuity that was offered to her. If the salon had a policy of �pooling� gratuities and distributing, even then, it would have been considerate (and good business practice) to have offered her, at the very least, a symbolic honorarium.
The concept of work-experience is to provide young people with an introduction to a business environment. Unfortunately, in this instance, your daughter also received an introduction to the life-experience process as well. With two children of my own who have participated in work-experience, their experiences were educational, nurturing and inspiring.
Whilst I feel badly for your daughter, it may be beneficial to sit down with her and share your frustration and anger, but also point out that this has been a valuable lesson for her as how not to run a business and how not to treat others.
I would suggest that both you and your daughter have a word with the school, to ensure they do not refer other children to the salon. Had there been a policy in place regarding work experience not receiving gratuities, and that was explained to her in advance, then the matter would be different.
Unfortunately, the percentages would typically be rather low that the manager of a hair salon would have a professional history of man-management skills and business ethics.
I might suggest that if any of these people your daughter served were friends, it might be beneficial to share with them what happened. They may have their own views on the matter which they might like to share with the shop owner.
Whilst indeed she is out a few pounds, your daughter has clearly had a good start on the fragilities of �the human condition.�
I wish you well
Fr Bill
