Japan is famous for its service. Waiters and waitress are attentive and prompt, and they don't even expect a tip! It's very easy to get accustomed to. But sometimes good service gets old. Sometimes otaku just want to be treated like crap.
Enter the tsundere cafe, where folks pay money to be treated like dirt. Maid cafes hit big in Tokyo's geek paradise Akihabara around 2003 and 2004. They were offshoots of pie-house Anna Miller's, which was a proto-maid cafe of sorts. Today, the popularity of Anna Miller's has subsided, but the uniforms worn by Anna Miller's waitresses are still iconic, inspiring costumes in countless video games, anime and manga.
