Hotel officials at London's One Aldwych transferred nearly $16,600 into the Polish dishwasher's bank account recently and apparently the accidental tip moved the man to rethink his employment status, The Mail on Sunday said.
The average pay for a kitchen employee at the hotel, whose guests have included film stars Jude Law and Nicole Kidman, is normally $500 a week.
But shortly after the bank payment was made in June, the dishwasher stopped showing up for work entirely.
As hotel officials attempt to resolve the situation through legal means, at least one of the dishwasher's former colleagues has applauded his apparent decision.
"What would you do if you spent every day washing rich people's dishes and then suddenly you went to the cashpoint and found you had eight grand in your account? I'd be off," the unidentified coworker told the newspaper.
