If you are visiting popular tourist attractions in downtown Vancouver, especially near Gastown, (next to Vancouver's Downtown Eastside a.k.a. "Canada's poorest postal code"), be prepared to have people involuntarily come up to you and want to tell about the history of the landmark and take your pictures. In the end, they will probably ask for donations.
Not that I am not compassion but it just leaves me with a disgusted feeling towards the neighborhood, the city, and the people.
Tourists (and naive locals), you have been warned.
