The Raijin stable is on tour in Osaka. They don't stay in a hotel but in a temple. Not to mention temples have cemeteries. Tanaka is scared of ghosts so he can't stand it. Takinokawa-zeki sends him on an errand, so he's glad to get out.
The sauce is for everyone to use.
Die Soße ist für jeden Gast. Du hattest
schon abgebissen, das ist unhygienisch!
La salsa está para que la usen todos. 
Ya lo mordió. No es higiénico.

Todo mundo vai usar este molho! É 
nojento mergulhar depois de ter mordido!
