The issue is that you are in a bunker. You are not entitled to free relief from a bunker. Within the constraint of staying in the bunker, you are entitled to free relief from the casual water itself.Surely the issue is that I am not in a water hazard, I am in 'casual water', which is an 'abnormal ground condition', and from which I should be entitled to free relief.
There is in fact a concession that, if you can't find full relief (as is required in all other situations), you may take partial (maximum available) relief. If there is literally nowhere in the bunker that is not under water, then the committee may declare that bunker to be all GUR and thereby removing its classification as a bunker. Free relief is then available.
