The Mayor would then pat the Brewer on the Shoulder telling him that it was okay and that after so many Grour Tastings they all taste alike, ad that he would follow up on his lead to the Grower, who would deny having ever giving bad produce to the brewer, stating "I han' pick each bar' me-self, Mayor, No-one bu me ever touches these things the lazy layabouts."
the Mayor then seized in
Dwarven Fury about other not pulling their weight would then order all of the other Growers to a hammering, after the hammering the Peasant who had drunk the bad Grour would be happy that justice had been served.
