Butler Service

Standard

He is ready at Satsuki Suite of a hotel in Osaka regular for Shin and Mei-Shun. If they order some items except for foods, he would put them into following space between a door and a closet. A little yellow light would be on among room phone buttons to inform guests that he served. However, he always appeared in person ringing the doorbell. What on earth do they mean??

Open this door,

and he serves.
