Highport Pawn Shoppe

You are in Highport's most fairly run pawn shoppe.
This shop always has a strange mix of people in it, ranging
from foreign travellers to winos from the the city gutters.
Unlike some fencing operations, this pawn shoppe will treat
its customers fairly. This shoppe also doubles as a recycling
center, so you may drop whatever you find for money. The
Highport sanitation department likes to keep its streets
clean, so they often subsidize the shoppe.
Obvious exits: east.
You see an abyssal ghoul.

I say we get rid of the drop command for pawn shops and make a "pawn" command that will sell it to you for as much as it can, and if the value is too low, give you 5g for it like dropping does now.

pawn all --> bam, sell what it can, and pawn the rest for 5g

or call it "recycle"
