A missive

[Mongo]

A clumsily-folded note is found lying on the bartop, the paper stained with charcoal fingerprints. The word "FIERHARE" has been labouriously scrawled on the front in an unskilled hand. Graphologists will note that the charcoal stick was gripped in the fist of the author, rather than held properly between the fingers.

Inside, the note reads in shaky block letters:

MONGO WANT TEND BAR. PROMIS TAK LEACHES OUT WATER.
-MOGNO

From the tone, it appears to be addressed to someone in a management position at the Tavern, possibly with red hair, assuming one reads through the misspellings on the front.
