Interestingly there was no coin box on the necks of the slaves
Interestingly there was no coin box on the necks of the slaves, as would be the case with “coin girls” in some cities, usually port cities, or coin dishes beside the mat, as in great camps, and such, in which coins might be left by clients or patrons. Indeed, I had not even given a tarsk bit at the entrance. These slaves were furnished as a perquisite of the camp, to content the men who might not have their own slave or slaves. The rent money given to Torgus for his girls then, as with others, was furnished by the Pani.
