If a shop or agency charges $350 or $400 instead of $250 they will get a bigger cut for themselves. More girls especially from overseas on working or study visas in Sydney are finding it difficult to find work in the workforce (this is coming from the girls themselves that I have met) and as a result, more are willing to work as WLs. You just have to check the rosters and notice more girls being added even though business is slowing down for some places.
