I remember some GIs returning from Europe in the 70s doing it. I could never see the reason - except maybe to hide the smell of the hash?

"except maybe to hide the smell"

Smell is not an issue in Amsterdam. I think that is just the way they do it. I went in to a 'coffee shop' there. Some specialize in weed, others in hash. When I was offered the latter, they presented it in this mixed manor. I didn't like it, either.
