The sign says that people got to take care of their bathhouse tickets.

The brewery I work in used to be a public bathhouse.

Funny they made a special sign for it.

I sometimes think we should make a sign to ask people to bring their glasses back inside.

But that always reminds me of a Dutch owned campsite in Belgium.
They had signs for everything.

Don’t put certain dirt in the bins at toilets.
No fire after a certain time.
At 8 the dustbin would be emptied. No dustbags were therefore accepted between 8 & ½ 9.
Payment should be done before 12. Otherwise one should be registered for another day.

Everywhere. Handwritten signs. Laws. You shouldn’t break.
