Apparently that happened in UK. The dentist is able to continue practising, as it happened a long time ago.

The GDC concluded he sought to impose a dress code on Muslim patients between April 2005 and June 2007. Butt "discriminated" against people and "did not act in the best interests of his patients" but it said the events took place "a considerable time ago" and he had not repeated the conduct since.

Well, no sanctions even. Worrying.
