I think that says it all, really.
Who wants to hear about my adventures at AKON?
You Are Not Japanese. Stop It.
Okay. I've come to terms with tween girls squealing out a shrill, badly-pronounced "KAWAII!" But stop pronouncing English words with Japanese accents. That guy in Death Note? His name is Light. Creator said so. STOP CALLING HIM 'RAITO' OR I'LL SMOTHER YOU WITH THAT RYUK PLUSHIE. Especially if you can't pronounce a Japanese 'R'. His name is Light. You're not Japanese. No one will ever think you are Japanese.
We also had someone ask for "Fake". They insisted on calling it "Fah-keh". Lord save me, I'd rather have the "Chawbits" and "My-Haim" people. IT'S NOT KAWAII, PEOPLE. IT'S NOT KAWAII AT ALL.
"Mayn-gas" bothers me too. It's mahn-ga(actually, mah-n-ga, I suppose), and the plural is the some as the singular. But I'll forgive you for that, since... you're not Japanese.
...that's really the only thing relating to the com. The rest is just Retail Pain x10. Although, yesterday we had random Naruto cosplayers in the store. Apparently, they dressed up as Sakura and Sasuka to go buy anime. What the hell?
