There is a logic to them wanting to see less clients to reduce risk and (hopefully) allow time to clean/sanitise in between.
Also if they all ration supply then they can charge higher prices
Market forces and supply and demand are strange bedfellows....
If the WG has a stable of regulars she can advise them of the price hike on the grounds of needing an increase for her to keep going/stay in business; and needing the extra pennies to cover Covid compliant costs.
However without a steady stream of regulars/fan boys the WG is gambling her reputation will in itself validate the price hike. If not she makes less money/even has dusty phone syndrome.
OFC; rationing supply should equate to higher prices, but this isn't always the case. It still needs the punter to see value in the exchange (paying £ for sex)...
Again, seeing less punters looks on the surface like it should limit her exposure to Covid. But in actuality, this isn't so..... If the WG see's 5 guys who are/have been in total isolation, then her exposure is minimal. Seeing 1 punter who has contact with 250 school kids a day massively increases her exposure..... So the numbers game isn't a good predictor.
As for sanitising between punters...some can't even be bothered to shower. Maybes a wipe down with a well used wet wipe is the limit many will go to.
