To my knowledge only Gigi charges 240, did the PO say she costs 240? If Kira is charging 240, then I won't see her anymore.
8 customers a day x 150 x ~300 days of the year (or more). Yes they earn more per year than all of you (or about all), and that is NET, because they don't pay tax on it. So the ones who don't get lost in drugs, retire with houses paid in cash, best cars, education for kids paid for, and plenty of investments if say they do it for 10 years (some less, some substantially more) x 2 (we lucky idiots in CA like handing over more than 50% of our salary to our governmental robbers). Most of them are not paying their own rent, and I believe food is minimal.
