The Street Value of Feijoas

I was walking back to work from a shop this afternoon when a random passerby asked "Are you into feijoas?" and opened his bag to show off a plastic bag full of them. At that point I was starting to wonder if I'd stepped into a bizarre Twilight Zone where fejoas were illegal street drugs and was going to ask if they were pure. Instead I opted to say "Uh, no thanks" and walk on before he started pushing oranges or something. Surreal!
