Oh, this is tremendous! Dude, I read that too and I somehow completely missed that.
The lek is legit too, however!
Okay, guys: how many drokna to a lek? I submit four. And then each drokna contains five dro’.
So five dro’ gets you a drokna, four drokna gets you a lek, and from there we just count up by number of leks.
(And one lek is an outrageous price to charge for a bottle of lemon water!)
