Best research suggests that about 20% of the US population has already been infected ([URL]https://covid19-projections.com/[/URL]). That contrasts with the roughly 6% confirmed cumulative case in the US due to the large proportion of asymptomatic cases and persistent undertesting. By all accounts the situation is Mexico at least as bad if not worse. And I would assume a HK girl is 3 x more likely to catch Covid than genpop so I would not be surprised by a 60-70% herd immunity for girls who've been working for more than a few months. As mentioned previously, its the mongers that you need to worry about. And I would also add the "farm-fresh" new girls to that list. These are the girls who are less likely to have developed immunity over the span of the last several months, so they are more likely to be sick right at the moment you are with them.
There is also the interesting dynamic of mongers themselves having more herd immunity than genpop. Mongers have a much higher appetite for risk in general, and if you're the type of person who is going to a HK speakeasy in the middle of a global pandemic then chances are you're not wearing masks in daily life, you're not careful with social distancing, etc - aka any monger that isn't dead is more likely to be immune (and thus less of a risk of passing it to you). Key phrase being "isn't dead" - we know mongers are also older and I'm guessing unhealthier so mongers are more likely to die from Covid.
All that to say - I'm unsure precisely how risky the HK speakeasy is. Of course, it's a perfect place to spread Covid if anyone has it. BUT... the people who are in the speakeasy are demographically less likely to be contagious. Personally, I wouldn't go in there without a vaccine.
