Both sides have reason

Ok let’s say that consuming poison is required and necessary for survival for a noble particularly their family since they’re well known, HOWEVER what’s with the butler saying “controlled amount etc.” Ain vomitted because of your so called controlled amount (╬￣皿￣)凸 and don’t nobles normally have poison tester or what and use silverwares to detect poison?? Just fucking carry an antidote everywhere ヽ(`Д´)ﾉ
