You fouled a guy who needs to be fouled. If he's going to the basket, you don't give a knick-knack foul and then argue with the ref. You foul him so he knows, so the next guy coming behind him knows, so his team knows you can't go in the lane.

From a good lie in the middle of a fairway bunker, I'll make the same swing as I do from an average fairway lie. I'll dig my feet in slightly and keep my lower body stable so I won't slip, but I don't change my club selection or setup. It's only when the ball is sitting down in the sand that I'll make some modifications.
