The front door. The client writes the request the way they’d DM it (“fade thursday after 5? my son needs one too”). Corner Chair reads the services, the people and the time window, shows only real open slots that fit, with the kid’s cut back to back with the parent’s, and books it in one tap: about 20 seconds instead of nine messages. If the window is full it offers the same window on the next open days, never an earlier time the client said they can’t make.
