I used to work in an American themed bar in Brussels, Belgium. Owner was American, staff were mostly American or British, customers were about 50% American/British/Australian/South African/New Zealander and the other 50% Belgian and a mix of every nationality under the sun.
After one particularly long night (we didn't close until 06:00 sometimes) I went to clean the toilets and found someone had punched a hole in the drywall.
On closer investigation I saw something unexpected in the gap so went to get a flashlight. In between the drywall and the outside brick wall there were 100's of needles. It turns out druggies had been using our bathrooms to shoot up, then standing on the toilet to drop their used needles over the top of the drywall where there was a gap between it and the ceiling.
The owner went batsh!t when he found out. He was very anti-drug.
We ended up with the drug squad placing cameras outside and inside the bar (no, not in the bathrooms) and then one night they pounced and arrested 15 people. 4 went to jail for dealing and the rest got busted for possession. After that the druggies seemed to move on to another bar.
We ended up with Stainless steel sheet walls and ceiling in the bathrooms and very bright lights.
Cleaning out those needles was a job I was dreading but the drug squad did it for us so they could do forensic tests.
On some nights cleaning the toilets made me
. Often the women's toilets were the worst!
Some people just need putting out of our misery!
