Cascus

Cascus is a character in Thermae Romae.

Overview
Cascus is a bath owner, but was starting to loose clients due to some germanic soldiers who got roman citizenship, but weren't following bath protocols and were chasing people away. Lucius Modestus managed to help him by putting bath manner instructions on the wall, so the germanic soldiers realized what they must do and started following them.

Later Cascus was part of a bath owners meeting, where they complained that Lucius was taking their clients, but Cascus explained that Lucius loved the old baths and even helped his. In the end Lucius ended helping all of the bath owners by introducing bath stamps for visiting a bath.
