at night, the coffeeshops close and the tourists come out, or they get sick smoking a joint, so they come out earlier, you catch them often at the kerkstraat, near leidsestraat (entertainment area).
throw avocado seed (available at the artists studio or bring your own)
think about the tension it will bring you! sex and violence!
watch barfing tourists while visiting a genuine artist studio!
get lucky and hit them with avocado seed
