The occasional tourist loiters near clusters of sex workers, before a furtive negotiation and a quick march to a nearby hotel, one of the few still open on Bangkok’s main tourist drag.
The already high risks of sex work have rocketed as the virus spreads.
Sex workers have flocked back to homes across the country in anticipation of several weeks of virtual lockdown before Thailand’s night economy comes back to life.
There are fears the malaise could last for months, yanking billions of tourist dollars from the economy and leaving those working in the informal sector destitute.
They include sex workers — an illegal but widely accepted part of Thailand’s nightlife.
There are concerns that a Thai government emergency scheme to give 5,000 baht ($150) to millions of newly jobless over the next three months will exclude sex workers because they cannot prove formal employment.
The Empower Foundation, an advocacy group for the kingdom’s sex workers, says entertainment venues make around $6.4 billion a year, many of them selling sex in some form.
Women are suffering the most from the virus measures, it says. Many are mothers and their family’s main income earner, forced into sex work by lack of opportunities or low graduate salaries.
The group has written an open letter to the government urging it to “find a way to provide assistance to all workers who have lost their earnings”.
As the 10 pm curfew looms, Pim and Alice prepare for a final forlorn patrol for customers.
“I think the government has been really slow. They don’t care about people like us who work in the sex industry,” Alice said.
“We’re more afraid of having nothing to eat than the virus.”
