Sacred Haven of Debauchery

Another guy saw me in person before, knew that he was bigger than me and better at swordsmanship, challenged me to a duel, and thought he wasn't risking anything. But I outsmarted him: I suggested using bottles of gasoline as weapons! He refused, which automatically put him on the same level as me (refusing to settle things with fists, with a 99% predictable outcome, is not less cowardly than refusing to settle things with an incendiary mixture, with a 50% predictable outcome).
