As well as condom and cigarette machines, the restrooms at the Weisse Bräuhaus on Tal now have vending machines for toothbrushes and toothpaste.
For €1 you get a mini toothbrush, a mini tube of paste, and a small beaker.

This means you can take a date for Schweineshaxen but still be kissing with confidence in the club later.
They should provide floss too, IMHO.
