When you enter Yoga Darsana, you enter through the back red door, place your shoes on the shoe rack, change if necessary, and walk into a lobby. Water and tea are available. You glance at the printout on the table to see if your series has elapsed, sign-in to attend class, pay for classes, if necessary and give payment to the teacher who places it in a basket in the armoire. Voila, class is ready to begin. The teacher, who has unlocked the studio, is ready to teach in the large asana room.
