The waiter, who volunteered for the job after another staffer refused, wore a transparent plastic apron, the thong and not much else, The Daily Mail reported.
The Woodland Houses home in St. Austell, is one of 18 operated by Cornwall Care, a charity that also provides daycare facilities in Cornwall for the elderly. Tracie North, director of operations and quality for Cornwall Care, said that staffers may have "overstepped the mark" when they granted her request to the "Make A Wish" initiative.
"The lady herself, her family and the member of staff who acted as her waiter believe that while it may have been a bit risque, the wish was carried out with the utmost respect for all those involved and taken in the good humored way it was intended by residents and staff present at the time," she said.
At least one staffer complained, sending a fax that asked if a woman would be asked to wear a bikini if a male resident made that request.
