As a builder/designer of pot bunkers I can understand the frustration some golfers can get from not being able to go forward when entrapped in ''the hazard'' however it is a hazard and should be avoided at all costs, just like water hazards and OOB and therefore no given right to get out without some kind of penalty.
I agree up to a point, but sometimes a bunker can be too harsh, IMHO.
We have a newly refurbished bunker on a 210 yd par 3. You have to play towards it and it's tucked on left side of green, and gathers balls short from left and right. The face is about 3-4 ft high but near vertical.
Because it's a links and plays firm, you cannot often hit and hold the green (even downwind it's usually a 5 iron+). So you can hit a shot which is nearly perfect, but catches the bunker and it typically finishes up against the front face. For a right hander, the only shot then available is to hit out to knee high rough.
Here I think the bunker should have had an angled face. It would still be a penalty because you'd need a great shot to get up and down, but as it is now you often have no shot, and a penaltly drop back in the bunker is the only option (and then you still have the tough up and down).
