还有一则Davos 大会的搞笑新闻 Sex Workers charge Davos attendees $2,500 a night as sex work demand booms Scores of sex workers have swarmed to the Swiss ski resort town of Davos to offer their services to the rich and powerful this week — with some said to be charging up to $2,500 a night. Every year, the World Economic Forum hosts a five-day gathering featuring CEOs, dignitaries, captains of industry, and media figures to discuss important global issues. A German sex worker took to Twitter to describe her experience mingling with the Davos crowd and their security detail. Her comments were reported by DailyMail.com. In 2020, a Swiss law enforcement official told The Times of London that at least 100 sex workers traveled to Davos in anticipation of the week-long event.
