Spot on.
There is a "hotel" near us, owned by Chinese, run by Chinese. All food is delivered from the same Chinese restaurant. All prostitutes are Chinese and delivered by the same cars.
The guests staying there all have luxury cars, Rolls Royce, Bentleys and so on. All very strong, short clipped hair. Sleep during the day. Wake up around 5 pm and do a couple of hours of heavy weight training and martial arts. Then they "do something" all night long. Cars coming and going every 30 minutes until 6 am when they decide to sleep.
