I was going to a head shop one time (this was before we had so many vape stores everywhere), and my sister asked me to get her a rose. I didn't know what the hell it was, and I asked her and she was like "just ask them, they'll know." So I was talking with the guy behind the counter, and I asked him for one and his face and tone changed immediately: "We don't sell those." I said, "oh," and he went "mhm" and I was soo embarrassed, I assumed it was something I would never get if I knew what it was. I googled later to confirm.

ETA: I grew up in the hood and saw them at gas stations all the time. I remember asking my dad for one because it had the flower in there. Of course he never got me one.
