My pet peeve is the diver who can't be bothered to listen to the dive briefing. It is soooo much easier to set expectations and review procedures before the dive than to try to handle problems on the fly.
A particular example relates to comunicating the amount of air remaining in your tank. In our dive briefing, we detail the procedure we use; flash one finger for one hundred psi, and only use one hand. So 2000 psi is communicated by flashing all five fingers four times.
The diver who doesn't listen to the briefing often flashes two fingers for 2000 psi. Two fingers usually will get me to shove my octo in your face until I can check your air gauge.
