I had a nice response all typed out and when I went to submit, my computer acted up. I'll try again. Try Billy Bob's patented exercise: shoot the object ball to just miss rolling into the pocket. Try to come as close as you can to making the ball without it going in. This will teach the touch necessary to shoot at pocket speed. There are tons of situations that require a finesse or touch shot to get shape on the next ball or work your way through a straight pool rack. Figure out some examples of shots that need a soft shot to get shape on the next ball and have your friend shoot them. May want to show him how it is done first. A good practice routine to learn the different speeds is the lag shot. Shoot the cue ball one length of the table, then 2, 3, and 4 lengths. The objects are to shoot straight and to try to make the cue ball end up within a diamond of the intended end rail. I played against a guy a few weeks ago that was shooting way too hard on most of his shots. He indicated that he knew he should shoot softer but he liked shooting hard. He got his butt whipped. As mentioned above, you do need to watch the table roll. I was playing in a bar last week and decided to try a safety. My object ball was about an inch off the end rail and my intention was to roll up, nudge my ball and leave the cue ball close to the rail and on the side of my ball that would leave my opponent the longest, toughest shot possible. The table rolled off so much that the cue ball missed my ball by a good inch or two (I was aiming for a center ball hit). My opponent then got ball in hand and ran out.
