Macau’s priciest boutique casino is sending its staff to Paris for butler training.

The Louis XIII boutique casino hotel isn’t slated to open until July 1, 2016 – or “mid-2016” according to recent filings – but its owners are taking steps to ensure that none of its very-VIP customers run the risk of getting slack service from frontline staff.

This week, Louis XIII Holdings announced that it had arranged a “specialized training session” for the casino’s would-be butlers with MCM Palace Consultants in Paris. A selection of Macau staffers were put through their paces by the MCM team, learning the finer points of service, etiquette and entertaining. The trainees will receive additional instruction from the Guild of Professional English Butlers.

Louis XIII plans to cater to only the ritziest of high-rollers, with a top hotel room rate of $130k per night and jewelry shops where the cheapest trinket will set you back a cool $1m. A year ago, the property ordered $20m worth of pimped out Rolls Royce Phantoms to ensure its guests’ luxury experience starts the minute they get off their private jet.
