Exclusive: Owner says private members venue is changing policy after revolt over division of pre-Christmas money

The restaurant tycoon Richard Caring has admitted his private members club Annabel’s made a “dumb mistake” after staff revolted over the use of more than £70,000 of their pre-Christmas service charge takings to pay managers’ bonuses.

Just one table of diners at the exclusive Mayfair venue, which has hosted celebrities, financiers and aristocrats ranging from Kate Moss and Harry Styles to the late queen, can spend more than £10,000 in an evening, according to workers.

Guests pay an optional 15% service charge, which goes to staff, and a further £3-a-head cover charge, which is kept by the company. The Guardian has seen evidence that Annabel’s, where a latte costs £6, a cheeseburger £26 and a ribeye steak £125, can collect more than £100,000 in service charges in just one week.

One member of staff said that “everyone got mad” when workers realised their share of the bumper service charge takings in the run-up to Christmas had been reduced by as much as £70,000 to hand bonuses to about 50 managers.
