Where I live you rarely find lamb in the grocery stores. And never goat meat. Now in the last decade or so, we've had a huge wave of immigrants move in who's main meat consumption is lamb and goat. So two different ranchers that I know have started raising them to take advantage of this opportunity. These new "citizens" like to be present during the slaughter. At the start, the ranchers told them ahead of time what the cost for the animals were and the customers agreed. After the animals were killed however, the customers always, always tried to renegotiate the price. Didn't take long for both of them to get the money beforehand.
To me, trying to haggle lower trophy fees after the shot is the same thing. Not cool.
