vorsprung durch technic

so after a day wandering sunny Frankfurt, including an insiders trip around the town hall and a brief nod to the mayoress, we obviously ended the day in a bar.
Our food and drink was delicious so we thankfully didnt need to use this strange contraption, which i was told (perhaps somewhat untruthfully) is called a vomitorium.
It is however definately intended for use as below.....

instructions for use

1. Face Vomitorium
2. Firmly grasp left handle in left hand
3. Firmly grasp right handle in right hand
4. Place face over bowl
5. Vomit, making sure to keep head down and vomit in the bowl
6. Once finished wipe mouth and return to bar
7. Repeat steps 1-6 as often as required
