Are You Being Served? Season 6 Episode 3

"Do You Take This Man?"

Mrs. Slocombe thinks she's finally got her man, a bouzouki player in a Greek restaurant. The staff plan a reception at the store to help keep costs down, and her American uncle plans on giving the happy couple a house. Before they can leave for the church, however, the best man arrives with bad news, forcing Mr. Tebbs to don the garb of a Greek vicar and Mr. Humphries that of the bridegroom.
