corporate settings, embassies, cruise ships, yachts, or within their own small "Rent-a-Butler" business or similar agency. Along with these changes of scope and context, butlering attire has changed. Whereas butlers have traditionally worn a special uniform that separated them from junior servants, and although this is still often the case, butlers today may wear more casual clothing geared for climate, while exchanging it for formal business attire only upon special service occasions. There are cultural distinctions, as well. In the United States, butlers may frequently don a polo shirt and slacks, while in Bali they typically wear sarongs. In 2007, the number of butlers in Britain had risen to an estimated 5,000. That number rose to 10,000 by 2014, consistent with increased worldwide demand. Training Butlers traditionally learned their position while progressing their way up the service ladder. For example, in the documentary The Authenticity of Gosford Park, retired butler Arthur Inch (born 1915) describes starting as a hall boy. While this is still often the case, numerous private butlering schools exist today. Additionally, major up-market hotels such as the Ritz-Carlton offer traditional butler training, while some hotels have trained a sort of pseudo-butler for service in defined areas such as "technology butlers", who fix guests' computers and other electronic devices, and "bath butlers" who draw custom baths. Gender and butlering Butlers have traditionally been male, and this remains the norm. Probably the first mention of a female butler is in the 1892 book Interludes being Two Essays, a Story, and Some Verses by Horace Smith. In it Smith quotes the noted writer and Anglican clergyman Sydney Smith, who between 1809 and 1829 struggled to make ends meet in a poorly paid assignment to a rural parish in Yorkshire: "I turned schoolmaster to educate my son, as I could not afford to send him to school. Mrs. Sydney turned schoolmistress to educate my girls as I could not afford a governess. I turned farmer as I could not let my land. A man servant was too expensive, so I caught up a little garden girl, made like a milestone, christened her Bunch, put a napkin in her hand, and made her my butler. The girls taught her to read, Mrs. Sydney to wait, and I undertook her morals. Bunch became the best butler in the country. Today, female butlers are sometimes preferred, especially for work within West Asian and Southeast
