“I politely suggested that the belay setup wasn’t ideal as the belayer would need to raise their arm up above their chest (see photo) in order to lock off the climber, and they may not be able to hold the fall. The climber assured me that they “do this all the time” and that the seconding climber wouldn’t fall anyway because the climbing was “so easy.”
