I guess it's about the eyeroll. People are going to be people. Do you want all those American visitors to know everything you do or do you want them to stop visiting I guess is the real question.
I want them not to say "the real one". All they have to say is "the one I'm used to". You don't need to know anything about food or history or sriracha to do that.
I roll my eyes at them, too. I don't know why people need to take their personal preferences and elevate it to some kind of moral universal thing.
But this post was about sriracha so I mentioned a sriracha anecdote.
