hey ed!
We got those hare krishnas in holland too!
they usually post around railway stations. I think I must look gullible too because they always hit on me. In exactly the same way: before you know it you have some books in your hand. last time they tried to make me accept some weird organic cookery book of some kind. I usually tell them I am not interested, but they are persistent indeed. “Uh, actually, would you mind giving one of those books back? We usually try to get a bit more for them.”
LOL!
