Yes, you wait.

Considering that you entered this shop and already "paid" for the esper's services, you decide it best to wait. You walk over and flip the OPEN sign so that CLOSED is outfacing. Now, you just need to wait. Scooping up the lithe man, you carry him to the back of the shop. There's a considerably nicely adorned bed in the room. All of it dyed a deep ultramarine. Approaching it, you lay the esper down gently. He may be a cocky twat but no need to rough him up anymore, well, for now. The bed is incredibly soft. A softly humming seemingly eminents from the bed. Its melody is soothing. You sit down on the bed and suddenly feel very, very drousey. It takes all your strength to move your body just enough to slip off the bed. Landing with a thud, you jolt back to being fully alert. The bed is obviously enchanted to induce sleep once laid in. It must be reacting to the esper laying in it ****. That's when you notice the faint soft blue glow. You're pretty surprised that the esper has such a marvel. A healing bed. You would have never thought such an item could be in this modest town.

You allow the bed to work its literal magic, and bide your time...
