Been here over 4 years. Sometimes I see little strips of card and cellophane with small blobs of something held in a line on the card in some local supermarkets. Finally I asked, and was told it was (what I translated as), chewing gum. I listened carefully as I left the shop, -no sniggering from the staff, so I assume they weren't pulling my leg.
Haven't plucked up the courage to try it though incase my translation was off. -Don't ask me what they said, it's lost in the mists of time (about 10 minutes, in my case).....
Anyone know what it is?
