I was 14 and selling lollipops in middle school. They were imported from Mexico so I can only assume why they were so addicting (kidding). Anyways, I was selling these suckers for $1.50 and sometimes $2.00 a pop when a pack of 40 was $5.00. Then I got called into the deans office and was told not to run a business in school. You already know my dumbass 8th grade self kept selling. I finally stopped after I was given several detentions.
Edit: Also, the lollipops were shaped as glass cups filled with beer so that's also why I got shut down...here is what they looked like https://www.amazon.com/Vero-Mexican-Tarrito-Flavored-Lollipops/dp/B003YW318Y
Tamarind candy from Mexico.
Especially since you could be enjoying a Tarrito instead. One of the best candies in the world.
These never made my tongue bleed personally, but these lollipops did (and still do).
