I had this image in my head of a huge tea house that mixed high end western style coffee houses and traditional japanese chashitsu for a short story I'm writing. The thing is, most japanese tea houses and rooms seem to be fairly small from what my research has shown, and I'm not sure who would be working there. Would there be geisha ? I read that was mostly female-dominated and the owner / boss is a man. What would the employees wear ? Western style clothes or kimono or ?? I'm sure it's all really subjective and I can obviously take some liberties but I want it to be believable to someone more familiar with Japanese tea ceremonies. Thanks !
