The Washington Convention and Visitors Association has named four service employes in Washington as the gold and silver award winners in its third annual Hospitality Service Awards Campaign. The program honors nonsupervisory personnel who work directly with the public.

The winners will be feted at an awards luncheon Thursday with Mayor Marion Barry Jr. at the Sheraton Washington Hotel. The purpose of the luncheon, said WCVA Executive Vice President Austin Kenny, is "to recognize those important front-line individuals whose daily practice of exceptional hospitality and service plays a key role in the continued growth of the area's tourism industry--the city's second largest source of revenue and jobs."

Samuel L. Humes Jr., Amtrak's Redcap foreman at Union Station, was the gold award winner and recipient of a $1,000 prize. Humes, a native of Washington and a fourth-generation Redcap, has been a Redcap at Union Station since 1941.

Silver award winners and recipients of a $500 prize were Charles S. Nillen, William E. Taylor Sr. and Glenn K. Unthank. Nillen is the banquet head houseman of the Four Seasons Hotel. He is a retired Air Force photographer and has been in Washington's hotel industry since 1970. Taylor is a taxi driver with the Capitol Cab Association. A native of Washington, Taylor has been a full-time taxi driver here for the past 37 years. Unthank is a passenger service agent with Delta Air Lines Inc. at National Airport. He has been with Delta for 11 years.

Nominations were received from WCVA subscribers, which includes about 1,000 employers in the local hotel, restaurant, transportation and related service industries, and local taxi drivers. The award selection committee and the judging panel included representatives from the John F. Kennedy Center for the Performing Arts, Delta Airlines Inc., Marriott Corp., the Mayor's Committee to Promote Washington, the Washington Convention Center, Tourmobile Inc. and the White House visitor's office.

The nonprofit Washington Cenvention and Visitors Association was founded in 1931 to market the greater Washington area as a convention and tourist destination.
