... why would a server at a bar need to know about tea? is it part of required knowledge for her workplace? no, its a BAR. you know about black or green tea, probably because it was a common drink with family and/or friends. if somebody else was raised in a different, tea-free family, and without tea-guzzling friends, at what point would they have been like "woah, i have to look into this whole tea thing" before working at the bar (where tea definitely isnt part of the training).
lets be honest, the reason you know about tea and she doesnt has nothing to do with intellectual curiosity. so take that high horse behind the barn and shoot it in the head, you wont need it anymore.
ok ok, i give up. trump won because of public ignorance to tea
